Abstract

A novel zero-voltage and zero-current soft-switching PWM DC-DC converter with low voltage and current stresses is presented in this paper. A new interleaved two switch forward converter topology is developed to minimize circulating current with no additional auxiliary circuits. This converter has many advantages such as less components, better efficiency, high power density and is cost effective for high power applications. The principle of operation is illustrated with steady-state analysis. Moreover, the effectiveness of the proposed converter topology is verified by a 500 W, 100 kHz breadboard
