This video is about How Class D Amplifiers Work part 1. This Class D amplifier uses GaN FETs from EPC. In this video I explain how the output stage works in a Class D and show how the square wave can reproduce a sign wave.

Class D Amplifiers are very efficient and can be made much smaller than a Class A/B amplifier of the same power. Also, this board that I am using is an eval card that was loaned to me by EPC to do these videos. #howclassDworks #howclassdamplifierswork #EPC #GaN #GaNFET
