Abstract :
In this paper, a lossless voltage clamp method with an auxiliary switch is proposed as a remedy for the high peak switch voltage of the class E amplifier. In the proposed method, the auxiliary switch is operated with synchronized drive circuit. Output power can be regulated by adjusting phase of auxiliary switch.
