400W MOSFET Amplifier Circuit With IRFP448

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.

  The final stage of the Current Gain Stage
  Also to what the name suggests this stage converts the voltage developed in the VAS
  and provides all the amps required to drive at 8 or 4 ohms. 2-ohm loads are possible
  for several minutes at a time. In fact, I have tested more than 1600 1kW amplifier
  Watts RMS at 2 ohms. But that would not be recommended as a long-term exposure at all.
  If it is higher than the figures of the STI-amp.
  Power to the AV amplifier 800
  The components of the power for this amplifier are as follows, and are favored
  A channel or a power module alone.
  1 toroidal transformer with a rating of 1kVA. Primary windings are made to fit
