Analysis and design of zero-voltage-switching class-E converter

In this paper, a new class-E DC-to-DC converter with half-wave controlled current rectifier is proposed. This is a high order multiple resonant converter whose circuit modes of operation have different resonant frequencies. The basic converter operation, detailed steady state analysis, steady state control characteristics and the peak values of inductance current and capacitance voltage are given. Based on the derived control characteristic curves, a design example along with a design procedure is demonstrated. The results are verified by PSPICE simulation. It is shown that this topology retains all the advantages of the conventional class-E converter and still provides zero-voltage-switching and results in low component stress values
