QUASI-RESONANT ZVS-PWM DC-DC FORWARD CONVERTER WITH ACTIVE CLAMPED CAPACITOR FOR SOLAR PHOTOVOLTAIC ENERGY-DRIVEN BOAT SYSTEM

This paper presents a novel prototype of active voltage clamped quasi-resonant ZVS-PWM forward DC-DC converter designed for specific low voltage high current application. We establish the soft-switching forward converter with a high frequency isolated link which can efficient operate over wide load ranges under conditions of zero voltage soft-switching and active voltage clamped switching. In addition, we evaluate connection of the soft-switching forward converter with large capacitor which capacitance is over 100[F].
