Contribution to the AC-analysis of resonant converters; analysis of the series-parallel resonant converter including effects of parasitics and lossless snubbers for optimized design

A stress analysis is performed based on the complex AC-analysis technique for half-bridge resonant power converters. Selecting the series-parallel topology (LCC) for high-power applications with low output voltage, the ideal and the lossy converter are analyzed in the time domain and evaluated by measurements and in comparison to the simplified analysis to find an optimum operating range and design.<<ETX>>
