50 watt power MOSFET amplifier circuit diagram


Posted on Feb 6, 2014

This is a MOSFET transistor based power amplifier circuit that can be operated between +35V to -35V range. The input voltage is pre filtered and pre amplified before applying to the MOSFET switch. The pre audio amplifier is a differential amplifier section with PNP transistor. What is differential amplifier A difference amplifier is a type of powe

r amp with two differential inputs which amplify the difference between two input signals. Here we are dealing with the circuit diagram and working of high voltage differential amplifier using IRF9530 and IRF530 MOSFET. You need a dual power supply circuit for this amplifier which I had posted earlier.
