Class DE inverters and rectifiers for DC-DC conversion

Abstract

A new family of Class DE inverters and related rectifiers is presented. Based on the Class D RF inverter, the circuits feature Class E switching transitions (zero voltage, zero dv/dt), giving low switching losses despite device capacitance and stored charge, combined with low voltage stress. Matching between inverter and rectifier is considered, time reversal duality is introduced and a family of inverters and rectifiers is presented. The circuits should find application in megahertz DC-DC converters.
