摘要

Isolated DC-DC converters are widely used as the essential power conversion equipment in recent renewable energy systems. At the same time, such converters are expected for wide input voltage range and fault tolerance. This paper proposes an isolated boost full bridge DC-DC converter with a set of low loss active snubber circuits. To verify the feasibility of the proposed scheme, a 10 kW prototype was developed for three-phase PV inverter system. Experimental result confirms the proposed converter's high efficient operation at 280-500 V input and resilient operation along 100-0-100% load change.
