Mosfet Amplifier Circuit for Subwoofer 400W

Leave a Comment
Power amp 400W IRFP448 Circuit
Amplifier circuit today,We would like to show you for the MOSFET 400 watt amplifier is amplifier on my kW shares the same circuit and basic PCB layout.
The only real difference is the number of output devices to the device.
We have using The IRFP448 design while the MOSFET amplifier 14 O / P devices.
These amplifiers can be used for virtually any application that requires high performance, low use Noise, distortion and excellent sound quality. Examples would be subwoofer amplifier should FOH stage
Amplifiers, surround a canal a very powerful sound amplifier, etc.
The 400W MOSFET-amplifier has four key stages of amplification. We are looking to start any Phase appropriate detail.
The bias and buffer stage
As the name suggests All Q ,C and ZD the Bias and buffer phases. Its main goal is to provide a stable MOSFET Gates and offset voltage and the voltage buffer amplifier stage of the High Resource capacity. What would have without the phase response and the effect
Slew rate is indeed very bad. The flip side of the coin is not the extra step
Introduction of an additional dominant pole in the amplifier feedback loop.
