800W Power Amplifier with Mosfet Final Transistor

Hello friends, in this post I will share a power amplifier circuit with the output power of up to 800 Watt using the final N-Channel and P-Channel MOSFET transistors.

Final Mosfet Transistor uses the IRFP240 series for N-Channel and IRFP924 for P-Channel. This power amplifier is very suitable for the Public Address audio system.

With a fairly large power up to 800W, this power amplifier is also suitable for the use of model speakers or woofers even suitable for subwoofer speakers.

For the use of certain speakers can also be added an active or passive crossover. For the subwoofer, you can also use the following subwoofer filter: Subwoofer Filter Circuit

And for the 800W power amplifier circuit you can see below with the PCB layout, and for clearer images, you can download the format. PDF at the end of the post.
