Power Amplifier with voltage regulator 4 × 50 Watt TDA8588

Leave a Comment
Power Amplifier with voltage regulator 4 × 50 Watt TDA8588
   The TDA8588 is a multiple voltage regulator combined with four independent audio power amplifiers configured in bridge tied load with diagnostic capability. The output voltages of all regulators except regulators 2 and 3 can be controlled via the I2C-bus. However, regulator 3 can be set to 0 V via the I2C-bus. The output voltage of regulator 2 (microcontroller supply) and the maximum output voltage of regulator 3 (mechanical digital and microcontroller supplies) can both be either 5 V or 3.3 V depending on the type number. The maximum output voltages of both regulators are fixed to avoid any risk of damaging the microcontroller that may occur during a disturbance of the I 2C-bus. The amplifier diagnostic functions give information about output offset, load, or short-circuit. Diagnostic functions are controlled via the I2C-bus. The TDA8588 is protected against short-circuit, over-temperature, open ground and open VP connections. If a short-circuit occurs at the input or output of a single amplifier, that channel shuts down, and the other channels continue to operate normally. The channel that has a short-circuit can be disabled by the microcontroller via the appropriate enable bit of the I 2C-bus to prevent any noise generated by the fault condition from being heard.
Speaker protection
    If one side of a speaker is connected to ground, a missing current protection is implemented to prevent damage to the speaker. A fault condition is detected in a channel when there is a mismatch between the power current in the high side and the power current in the low side; during a fault condition the channel will be switched off. The load status of each channel can be read via the I 2C-bus: short to ground (one side of the speaker connected to ground), short to VP (one side of the speaker connected to VP), and shorted load.

Muting 
    A hard mute and a soft mute can both be performed via the I 2C-bus. A hard mute mutes the amplifier within 0.5 ms. A soft mute mutes the amplifier within 20 ms and is less audible. A hard mute is also activated if a voltage of 8 V is applied to pin STB. 

Temperature protection 
     If the average junction temperature rises to a temperature value that has been set via the I2C-bus, a thermal protection pre-warning is activated making pin DIAG LOW. If the temperature continues to rise, all four channels will be muted to reduce the output power (soft thermal clipping). The value at which the temperature mute control activates is fixed; only the temperature at which the thermal protection pre-warning signal occurs can be specified by bit D4 in instruction byte 3. If implementing the temperature mute control does not reduce the average junction temperature, all the power stages will be switched off (muted) at the absolute maximum temperature Tj(max)

60W MosFet Audio Amplifier

Leave a Comment
High Quality, powerful unit: 90W into 4 Ohm load Also suited as guitar or bass amplifier
60W MosFet Audio Amplifier
60W MosFet Audio Amplifier
60W MosFet Audio Amplifier Description



To celebrate the hundredth design posted to this website, and to fulfil the requests of many correspondents wanting an amplifier more powerful than the 25W MosFet, a 60 - 90W High Quality power amplifier design is presented here.
Circuit topology is about the same of the above mentioned amplifier, but the extremely rugged IRFP240 and IRFP9240 MosFet devices are used as the output pair, and well renowned high voltage Motorola's transistors are employed in the preceding stages.
The supply rails voltage was kept prudentially at the rather low value of + and - 40V. For those wishing to experiment, the supply rails voltage could be raised to + and - 50V maximum, allowing the amplifier to approach the 100W into 8 Ohm target: enjoy!
A matching, discrete components, Modular Preamplifier design is available here:Modular Audio Preamplifier.
Notes:
  • In the original circuit, a three-diode string was wired in series to R10. Two of these diodes are now replaced by a red LED in order to achieve improved quiescent current stability over a larger temperature range. Thanks to David Edwards of LedeAudio for this suggestion.
  • A small, U-shaped heatsink must be fitted to Q6 & Q7.
  • Q8 & Q9 must be mounted on large heatsinks.
  • Quiescent current can be measured by means of an Avo-meter wired in series to the positive supply rail and no input signal.
  • Set the Trimmer R10 to its minimum resistance.
  • Power-on the amplifier and adjust R10 to read a current drawing of about 120 - 130mA.
  • Wait about 15 minutes, watch if the current is varying and readjust if necessary.
  • The value suggested for C1 and C2 in the Power Supply Parts List is the minimum required for a mono amplifier. For optimum performance and in stereo configurations, this value should be increased: 10000µF is a good compromise.
  • A correct grounding is very important to eliminate hum and ground loops. Connect to the same point the ground sides of R1, R3, C2, C3 and C4 and the ground input wire. Connect R7 and C7 to C11 to output ground. Then connect separately the input and output grounds to the power supply ground.

45 Watt Class B Amplifier

45 Watt Class B Amplifier Description
45W into 8 Ohm - 69W into 4 Ohm Easy to build - No setup required
45 Watt Class B Amplifier
45 Watt Class B Amplifier
45 Watt Class B Amplifier Description



The main design targets for this amplifier were as follows:
  • Output power in the 40 - 70W range
  • Simple circuitry
  • Easy to locate, low cost components
  • Rugged performance
  • No setup

These goals were achieved by using a discrete-components op-amp driving a BJT complementary common-emitter output stage into Class B operation. In this way, for small output currents, the output transistors are turned off, and the op-amp provides all of the output current. At higher output currents, the power transistors conduct, and the contribution of the op-amp is limited to approximately 0.7/R11. The quiescent current of the op-amp biases the external transistors, and hence greatly reduces the range of crossover.

The idea sprang up from a letter published on Wireless World, December 1982, page 65 written by N. M. Allinson, then at the University of Keele, Staffordshire.
In this letter, op-amp ICs were intended as drivers but, as supply voltages up to +/- 35V are required for an amplifier of about 50W, the use of an op-amp made of discrete-components was then considered and the choice proved rewarding.

The discrete-components op-amp is based on a Douglas Self design. Nevertheless, his circuit featured quite obviously a Class A output stage. As for proper operation of this amplifier a Class B output stage op-amp is required, the original circuit was modified accordingly.

Using a mains transformer with a secondary winding rated at the common value of 25 + 25V (or 24 + 24V) and 100/120VA power, two amplifiers can be driven at 45W and 69W output power into 8 and 4 Ohms respectively, with very low distortion (less than 0.01% @ 1kHz and 20W into 8 Ohms).

This simple, straightforward but rugged circuit, though intended for any high quality audio application and, above all, to complete the recently started series of articles forming the Modular Preamplifier Control Center, is also well suited to make a very good Guitar or Bass amplifier. Enjoy!
Notes:
2N3055 and MJ2955 transistors were listed for Q8 and Q9 as the preferred types, but many different output transistors can be used satisfactorily: TIP3055/TIP2955, TIP35/TIP36, MJ802/MJ4502 amongst others.
Discrete op-amp output transistors Q6 and Q7 do not require any heatsink as their cases remain at ambient temperature. Power transistors Q8 and Q9 should be mounted on a black, finned heatsink as usual.

18W Class-B Audio Amplifier with Tone Controls


In order to satisfy repeated requests by correspondents, a medium power audio amplifier incorporating tone controls in the feedback path was finally designed.
To avoid an excessive increase in parts-count, due to the addition of the tone controls, a simple amplifier circuitry was designed on the same guidelines of the successful 45 Watt Class B Amplifier, but using the excellent NE5534 IC instead of a discrete component op-amp to drive the output "dumper" transistors.

The particular circuit configuration, allowed to push the NE5534 exceptional capacity of driving the output transistors near to its limits, enabling the whole amplifier to deliver relatively high power outputs without problems. For this reason, it was possible to obtain 18W into an 8 Ohm load using a power supply voltage of +/- 20V.
Despite the complication added by the tone controls, the amplifier has an input sensitivity of 130mV RMS, allowing to connect directly to its input the most disparate audio sources without the need for a separate preamplifier.
Total Harmonic Distortion figures are astonishingly low, much lower than comparable audio amplifiers using a single-IC audio amp.

An interesting feature of this amplifier is the absence of any kind of setup.

The power supply is straightforward. The parts values suggested are suited to power a stereo version of this design. For a mono amplifier a less powerful mains transformer can be used, having a 30V Center-tapped or 15 + 15V secondary winding, rated at about 24 to 30VA or 0.8-1A.

Notes:
Q1 and Q2 power transistors should be mounted on a finned heatsink of at least 100x50x25mm.
+ and - 22V is the absolute maximum permissible voltage supply for NE5534: please do not exceed this limit.
In the event you obtain a higher voltage from your power supply, you can consider the use of a regulated supply. Please see Simple, Efficient, Regulated Power Supply.

Battery Level Indicator 36 Volts Schematic Circuit

Battery Level Indicator 36 Volts Schematic Circuit

Battery Level Indicator 36 Volts Schematic Circuit
Battery Level Indicator 36 Volts Schematic Circuit
This battery level indicator offers (5) LEDs that light up progressively as the battery voltage increases. This is a update of the 24V Battery Level Indicator.
While designed for 36V systems, it is easily modified to 24V, 48V or 60V simply by changing two resistors.
LED ColorCharge Level
Red:Power Connected (0%) (essentially always on)
Orange:Greater than 35V (25%)
Yellow:Greater than 37V (50%)
Green:Greater than 39V (75%)
Blue:Greater than 41V (100%) (full charge is about 41 to 42V)
Of course, you may select your own colors if desired.

High voltage issues
One limiting factor is the LM339 that has an absolute maximum voltage rating of 36V –and it is not good practice to operate near that point. The solution involves running the IC power rail off a zener shunt regulator. Shunt regulators are very simple, inexpensive and robust –good for this application. However, the LM339 open collector outputs cannot drive LEDs powered from the battery bus due to the same maximum voltage limitation. There are two solutions for this: increase the current rating of the shunt regulator so that it can power the LEDs, or run the LEDs via a cascode amplifier arrangement –I chose the cascode amplifier.
Cascode amplifier
A cascode amplifier is a configuration where one transistor feeds a 2nd transistor that is connected in the common base configuration. This configuration is generally used for RF amplifiers. In this circuit it offers one great property –low voltage in, high voltage out. By tying the bases of these transistors to the 13V bus, the LM339 open collector drive transistors never see more than 13V. However, the cascode transistors may drive LEDs that are tied to a much higher voltage –up to 80V using the MPS-A16. By limiting the emitter current, the LED current is automatically limited to the same value. While this is relatively busy, it places virtually no burden on the shunt regulator.
Circuit Operation
D1 is the voltage reference zener. Tied to this is a string of divider resistors (R2-6) that set the various fixed voltage levels. R7 & 8 form a voltage divider to that divides the battery voltage by a factor of 9. The quad comparator compares the various voltages from the two dividers.
For calibration, connect to a voltage source that can be set to the highest LED threshold (41V in this case). Then adjust the calibration pot until D2 flickers. The remaining LEDs will switch on close to the indicated voltage –accuracy of those voltages may suffer slightly, but should be close.
The LEDs are biased to operate at 2.3mA which is reasonably bright for high efficiency LEDs. This current can be adjusted simply by varying the emitter driver resistors (R9 through R13). To reduce standby power, a push-to-test pushbutton may be used.
Bug
Testing on variable voltage turned up an interesting bug –when the voltage was turned down to about 10V, all LEDs lit again. This was traced to Zener D9 dropping out of conduction thus starving the voltage divider. Connecting a 33K resistor across D9 corrected this little problem without affecting anything else.

SAVING ENERGY IN YOUR HOME 100 Tips To Save Energy
SAVING ENERGY
SAVING ENERGY

1. It begins with your commitment. If you want to save energy, you have to be committed enough in doing the necessary things for it. Without your commitment, you may not become mindful of you actions, which can directly or indirectly affect your overall energy consumption. Thus, you have to be committed, so that you can see results on it. 

2. Make it a practice to turn off the lights in your room. Lots of people today leave their bedrooms without turning the lights off. Although lights do not consume much electricity, lots of energy would be wasted if you constantly left them turned on for the most parts of the day, even if you are not inside the room. Thus, make it a practice to turn off the lights, so that you can save energy. 

3. Replace your filters regularly. Most heating and cooling equipment require clean filters, in order for them to run clean. The filters can also help them in becoming more energy efficient. With that, replacing your filters regularly can help you save a lot in terms of energy consumption. Ask your technician about it, so that you would know when is the best time to do so. 

4. Dirty coils make your appliances consume more electricity. Refrigerator coils can get dirty over a certain period of time. In most cases, they can accumulate a lot of dirt within the six month period; and, when that happens, the dirty coil would make your refrigerator work harder in order to achieve its desired temperature. Thus, it is best if you practice cleaning and vacuuming your refrigerator coils every six months or so, so that you won’t have to endure higher electricity bills. 

5. Close the windows. Whether you need to achieve lower or higher temperature inside your house, it is best if you close your windows. This is because, open windows would make your cooling or heating equipment require more energy to serve you better. When you close the windows, your equipment would not work too hard, which means it can help you save energy. 

6. Do not forget the timer. When you sleep at night and you are using your air-conditioning system to make your room temperature cooler, it is a good idea to make use of its timer. The timer would ensure that your AC would be turned off in time. Aside from that, if you won’t use the timer, you may get tempted to extend its usage, especially when you don’t feel like going out of your bed yet. 

7. Make use of solar energy. There are lots of DIY solar panels that you can make use for your home today. One of the best things about this new technology is that, you no longer have to pay high electricity bills with them. All you have to do is to have someone install it properly, and you should be good to go. 

8. Dry your clothes the natural way. One of the best ways to conserve energy is to dry your clothes naturally. If you are going to use your washing machine’s dryer for them, then you would be consuming lots of energy. Just hang the clothes outside, and let the sun dry it so that you can save more energy. 

9. Unplug all unused appliances and electronic devices. You need to keep in mind that many appliances and other electronic devices consume electricity when they are plugged into the socket, even when they are turned off. Thus, the moment that you turn them off, you should ensure that they are unplugged. If it is a hassle for you to do, then just do it just before going to bed. 

10. Your computer monitor. If your computer’s monitor is still the large type, or the CRT, then it is time to replace it. CRT screens actually consume more energy than the LCD types. Thus, it is time to make use of the newer computer screens. Aside from consuming lesser amounts of energy with them, it also improves your whole experience in using your desktop PC. 

11. Open up your windows during summer. Summer heat can be hard to beat, which is why it is best to come up with ways to get around it without consuming lots of energy. Open up your windows during summer time, so that you can let fresh air go in and out of the house. This is effective, especially if your house is surrounded with trees. 

12. In going for a vacation. When you go for a vacation, you need to make sure that all the appliances, except the refrigerator, are turned off and unplugged. Aside from that, if you have a water heater, then you should also ensure that it is turned off as well. Minimize energy consumption by leaving just a light in the porch and in your living room while you are away. 

13. Minimize the number of times you open the door. When it is warm and you are using your air-conditioning to achieve cooler temperature inside your place, then you should minimize the times that you and other members of your household are opening the door. Each time you open the door, warm air would get inside your place. When that happens, it would make your cooling equipment work harder. 

14. Turn off your light when you go to bed. Turning off the light inside your bedroom when you go to bed can help save lots of energy. If you are not very comfortable, you can always use a lampshade instead or a night light. When you do this, aside from saving energy, it can also help you sleep better. 

15. Using water heater. If you have a water heater installed at your place, it can make your energy consumption go up, if you have leaky faucets. Thus, you should fix any leaky faucet as soon as you spot them. Aside from saving energy, it can also help you save on water usage. 

16. Cut off cooling areas in your house that don’t need it. When you turn on your cooling equipment at your place, you have to consider the fact that it would try to lower down the temperature on the entire space. Thus, if you have rooms that don’t need cooling, then you should close the door to that room. By minimizing the space that it has to cool down, you are ensuring that it would not consume more energy that it needs to. 

17. Block the summer light to save energy. Blocking the summer light can go a long way, as far as saving energy is concerned. This is because, it can help in bringing down the temperature inside your house. Thus, you need to install awnings, shades, blinds, or sunscreens in spots where sunlight can enter. Reflect away the heat from your house to make it cooler. 

18. Have a technician check your electric wirings on a regular manner. Checking your electric wirings inside your house is necessary, in order to lessen energy consumption. Routine check up would ensure that no wires are damaged by pests, which can cause more energy consumed or even short circuit. Thus, this practice would not just conserve energy, but also make your home safer as well. 

19. Installing an exhaust fan in your kitchen. Whenever you are cooking, an exhaust fan inside your kitchen can help a lot in blowing hot air from the place. This can help you save a lot of energy especially during summer time. Your savings when it comes to using energy to cool down your place would be more than the electricity consumed by the fan. 

20. Air dry your dishes whenever you can. Using the dishwater heater consumes a lot of energy. Thus, it is best if you turn it off, whenever you leave your place and also when you are not making use of it. Aside from that, it is also a good idea to simply air dry your dishes whenever you can or when you have the time for it. 

21. Be mindful of your cooling system’s thermostat levels. It is best to be mindful of your cooling system’s temperature or thermostat levels. This is because, it can determine the amount of energy that it would consume in cooling down your place. Thus, you should take note of the comfortable temperature that you want to achieve, so that you won’t go lower and consume more energy in the process. 

22. An alternative to using your air conditioning system. If it is warm and you don’t want to turn on your air-conditioning system for a while, you can make use of an alternative for it. All you have to do is to place a bowl that is filled with ice cubes in front of your electric fan. Turn on the fan, and you can feel cool air blown towards you. 

23. Reduce the humidity inside your place. Reducing the humidity inside your place can greatly help in making you more comfortable during warm weather conditions. To achieve that, all you have to do is to use a dehumidifier. When you make use of it, you can minimize the number of times that you have to turn on your airconditioning system. 

24. Use your air-conditioning system’s timer. It is a good idea to make use of your air-conditioning system’s timer on a regular basis to save energy. For example, when you turn it on at night before going to bed, set the timer to turn off the system by dawn. This is because, it is usually pretty cold during that time, and you won’t even notice that your AC has already been turned off. 

25. Minimize the use of your shower’s heater. There are times when people make use of their showers’ heater even on summer times. Thus, whenever it is warm, you should see to it that your shower’s heater has been turned off. Do this, so that you can enjoy cooler water, and save on energy consumption. 

26. Minimize the times your kids open up the fridge. Whenever you open the door of your refrigerator, its cool air would go out and warm air would go in. Therefore, it can make your fridge work harder, and consume more energy because of it. Thus, you have to remind your 7 kids not to open up the fridge a lot. Aside from that, let other members of your household be aware of it, so that they can all help out. 

27. Purchase an air-conditioning system that can help you conserve energy. There are air-conditioning systems today, which are designed to help you conserve energy. One example of it is that, it has a plug that comes with a socket in it, in which you can plug your fan into. With that, once the timer turns off the system, your fan would automatically be turned on, so that you won’t even have to get up of your bed to do it. 

28. Buy more food items to place inside your refrigerator. Keep in mind that a cooling system usually works harder with larger space. Thus, if your refrigerator is half empty, then it needs to consume more energy to cool it down. With that, you should try to consume more space inside your refrigerator, so that you would be able to save energy. 

29. Turn off your computer. Lots of people think that when they turn their computer off and on, it would wear out the system faster. However, it is actually untrue, especially with the newer computers. Thus, it is time to make it a practice to turn off your computer whenever you are not using it, so that you can bring down your electricity bills.
