Mosfet Audio Power Amplifier Circuit Diagram

Do not expect much performance from this amplifier.

Mosfet audio power amplifier circuit diagram.

Power amplifier is the part of audio electronics. 100 watt power amplifier circuit using mosfet audio. Go to top of list. Capacitors c3 c4 c5 must be rated 50v and c2 can be 10v.

How to make an audio amplifier using just one mosfet transistor. The circuit will give you more than 600 watt audio output for speakers with impedance of 4 ohm. Use 30v dc for powering the circuit. This is the circuit diagram of 600w mosfet power amplifier.

50 watts mosfet amplifier. By sourav gupta oct 17 2018 0. The power supply used for this single mosfet class a power amplifier circuit is 18vac and 160va ei transformer attached to a bridge rectifier of 25 amp to generate dc power of 24 volts. 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.

Different types of mosfet amplifier circuits with diagram and schematicsa list of various audio amplifiers of output 10 watts18 watts50 watts using mosfet. To filter and smooth the power we used 10000µf capacitors and hammond make 10mh choke of 5 amp over pi filter setting cap choke cap. In sound electronics the operational amplifier increases the voltage of the signal but unable to provide the current which is. A power amplifier circuit using mosfet has been designed to produce 100w output to drive a load of about 8 ohms.

It is designed to maximize the magnitude of the power f given input signal. 100w to 8 ohm speaker 160w to 4 ohm speaker low distortion. 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. Use a 8 ohm 15w speaker as the load.

The circuit can be assembled on a vero board.
