600W MOSFET Power Amplifier

600W MOSFET Power Amplifier
This is the circuit diagram of 600W MOSFET power amplifier. The circuit will give you more than 600 Watt audio output for speakers with impedance of 4 Ohm. This high power amplifier circuit uses 6 pieces of N-channel MOSFETs IRFP450 in the output stage alone and will give you about 400Watt power. To make more than 600Watt, then you need to use 12 pieces of N-Channel MOSFETs IRFP450. One of the construction sequence to produce more output power of

MOSFET Power Amplifier 5200W IRFP250

MOSFET Power Amplifier 5200W IRFP250
This is the circuit design of Mosfet power amplifier 5200W RMS, the schematic is for single channel. The circuit uses 16x IRFP250 to gain 5200W RMS power output at 2 ohms load. To feed this circuit , you will need 150 volts dual polarity (symmetrical) power supply of course with very high DC current. (more…)

Amplifier Circuit using MOSFET Output Stage

Amplifier Circuit using MOSFET Output Stage
The circuit presented here is amplifier circuit using MOSFET output stages, as a substitute for the output stage based on bipolar transistors. This project is for those who want to experiment with the power MOSFET. Without going into details, the MOSFET has a characteristic sound of vacuum tubes and bipolar transistors. The main advantages MOSFET Amplifier : simplicity of operation, hundreds of watts with a simple parallel, negative temperature coefficient and fast switching times. The main disadvantages : a

25 Watt Power Amplifier based MosFet

25 Watt Power Amplifier based MosFet
25 Watt power amplifier based MosFet,  can be connected directly to the signal source and does not require pre-amplifier to drive. The amplitude of the input signal must reach the level of 200 mV. This signal is normally present on the linear output recorder, CD player, computer sound card and other devices. To adjust the volume can be placed at the entrance to the potentiometer 10 kohm. Trimmer adjustable quiescent current. It must be within 100 mA. (more…)
