| Abstract: | Under developing four different modes of operation of the push pull zero voltage switching multiresonant converter (PP ZVS MRC), a complete DC analysis is presented. A computer simulation is programmed to calculate the DC voltage conversion ratio characteristics and to facilitate the circuit design of the push pull multi resonant converter. A 50 W off line PP ZVS MRC is designed and implemented. The analysis is verified experimentally. |
