Abstract

This paper proposes a zero-voltage and zero-current switching (ZVZCS) DC/DC converter characterized by 1) capacitive output and 2) input-series output-parallel (ISOP) structure for the high input voltage and high power applications. The proposed converter can reduce the circulating current and duty cycle loss in comparison with the conventional converter with the inductive output. More significantly, the proposed converter can also effectively reduce the ripple current on the secondary clamping capacitor. Therefore, the proposed converter can improve the reliability of the secondary clamping capacitor. The characteristics and performances of the proposed converter are analyzed in detail. Finally, the simulation results verify the proposed converter.
