Abstract :
This paper presents a novel circuit topology of a voltage source type zero voltage soft-switching full bridge inverter DC-DC power converter with an isolated high-frequency transformer link this power converter incorporates zero-current soft-switching (ZCS) mode phase-shifted PWM active power switches in series with diode into two diode arms of full-bridge rectifier or center-tapped rectifier in transformer secondary-side. This isolated DC-DC power converter circuit can achieve ZVS/ZVT transition commutation for non-controlled active power switches in the primary side of transformer and ZCS/ZCT transition commutation for phase-shifted PWM active power switches in the secondary side of transformer, which can operate under wide load variations from a light load to a heavy load as well as a condition of PWM voltage regulation strategy.
