100W MOSFET Power Amplifier based on IRFP240

A 100W MOSFET power amplifier circuit based on IRFP240 and IRFP9240 MOSFETs is shown here. The amplifier operates from a +45/-45 V DC twin supply and might deliver 100 watt rms into an 8t ohm speaker and 160 watt rms into a 4 ohm speaker. This Hi-Fi amplifier circuit is appropriate for lots applications like general purpose amplifier, guitar amplifier, keyboard amplifier. The amplifier and also

Audio amplifier MosFet 18W-30W

This project was a kind of challenge: design an audio amplifier capable of delivering a decent power output with a minimum parts count, without sacrificing quality. The section of the power amplifier employs only three transistors and a handful of resistors and capacitors in a configuration of shunt feedback but can deliver more than 18W in 8 ohms with < 0.08% THD @ 1 kHz at the beginning of the

10 Watts Mosfet Audio Amplifier

The diagram shown here is a MOSFET amplifier circuit 10W of sound that only requires a single source. Single railway material rarely used in power amplifiers class-B. However, for low power applications like this is very thin. Actually I have this circuit a old cassette player is still working and republish as it is. The BD512 and BD522 power MOSFETs is obsolete now and you can use any other

50 Watts Mosfet Audio Amplifier

50 Watts Mosfet Audio AmplifierThe first stage of the amplifier is a differential amplifier based on transistors Q1 and Q2. Capacitor C8 is the dc input coupler, C1 R1 limits the input current and capacitor passes high frequency signals. The second stage is the stage driver consisting of transistors Q3 and Q4. Output stage is a complementary push-pull stage based MOSFETs IRF530 and IRF9530.
