Mosfet Audio Amplifier Schematic Diagram

100w to 8 ohm speaker 160w to 4 ohm speaker low distortion.

Mosfet audio amplifier schematic diagram.

The power amplifier circuit designed here has the advantage of being more efficient with less cross over distortion and total harmonic distortion. This filter section is created using the r3 r4 and c1 c2. Use 30v dc for powering the circuit. The circuit will give you more than 600 watt audio output for speakers with impedance of 4 ohm.

At the beginning of the first stage amplification a filter section blocks unwanted frequency noises. This is the circuit diagram of 600w mosfet power amplifier. Different types of mosfet amplifier circuits with diagram and schematicsa list of various audio amplifiers of output 10 watts18 watts50 watts using mosfet. An audio power amplifier or power amp is an electronic amplifier that strengthens low power inaudible electronic audio signals such as the signal from radio receiver or electric guitar pickup to a level that is strong enough for driving or powering loudspeakers or headphones.

Use a 8 ohm 15w speaker as the load. A power amplifier circuit using mosfet has been designed to produce 100w output to drive a load of about 8 ohms. Do not expect much performance from this amplifier. Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v.

Hi fi 100w mosfet power amplifier circuit. 100w audio amplifier circuit diagram and explanation the schematic for this 100 watt audio amplifier has a few stages. 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.
