In addition to inheriting the advantages of the current-fed push-pull converter, the proposed converter has several features, for instance, low voltage stress on the semiconductor and the recovery of the leakage energy. Consequently, low voltage rating MOSFET can be used resulting in achieving high conversion efficiency. Moreover, high power density is also achieved because the capacitance as well as the number of the output filter capacitor is significantly reduced. To demonstrate the feasibility of the proposed converter, the operation principles as well as the experimental results with 150 kHz, 36-75V input and 380V/500W output are described in this thesis.
