A novel resonant converter topology and its application

This paper describes a secondary side resonant converter with particular suitability to step up and high power applications. A description of the basic circuit is followed by a detailed description and some important developments building upon the basic circuit, including inversion and bi-directional configurations. Efficiency is very good (/spl ap/94%) as a result of the zero voltage switching and zero current switching operation, and this is demonstrated with test data for two prototype configurations from 1 kW to 6 kW.
