A new semi-analytic approach for class-E resonant DC-DC converter design

Abstract

This paper presents a new approach for the design of a class-E resonant DC-DC converter. The small number of passive components featured by the considered topology allows to exactly solve the differential equations regulating the circuit evolution, and to develop a semi-analytic design procedure based on the differential equations solution. This represents an important breakthrough with respect to the state-of-the-art, where class-E circuit analysis is always based on strong simplifying assumptions, and the exact circuit design is achieved by means of numerical simulations after many time-consuming parametric sweeps
