COMPARISON OF RESONANT CONVERTER TOPOLOGI ES

In this article we present a comparison of resonant converters operati ng above the resonant frequency of the oscillating circuit. The conver ters under consideration are the two basic structures (the series reso nant converter and the parallel resonant converter) as well as the ser ies parallel resonant converter with capacitive filter. For each of th ese structures, the state equations of each operating sequence are for mulated and theoretical and experimental results are presented for com parison. We conclude by outlining a 1-kW module for each structure.
