Abstract

A generalized steady-state analysis of resonant converters using a two-port model and Fourier-series approach is presented. Analysis is presented for both voltage-source (VS) and current-source (CS)-type loads. Analysis can also be used either for variable-frequency (half- or full-bridge) or fixed-frequency (phase-shift control for full-bridge) operation. Steady-state solutions have been obtained. Particular cases are considered to show the method of application in analyzing different schemes. A simple design procedure is given for two particular cases to illustrate the use of analysis in obtaining design curves and in designing the converters. Experimental results obtained from a MOSFET-based 500-W fixed-frequency LCL-type resonant converter are presented to verify the analysis
