UNIFIED APPROACH TO THE ANALYSIS AND DESIGN OF RESONANT CONVERTERS Part Ⅱ-Continuous Conduction Mode in Higher Order Converters

摘要

In this paper,we present the analysis and design of a generalized half-bridge parallel resonant converter(PRC)operating in the continuous conduction mode.All possible converter topologies for 2nd,3rd and 4th order PRC are given.We show that these circuits can be analyzed in terms of simple two-dimensional state-plane diagrams.To illustrate our analytical approach,the detail analysis of a 4th order LLCC-type PRC is presented.
