Due to the increasing demands of safe and efficient renewable energy systems, isolated DC-DC converters became widely used in this field as the essential power conversion blocks. At the same time, such converters are demanded for wide input voltage range and fault tolerance as desirable features. This paper proposes a isolated boost full bridge DC-DC converter which features wide input range and resilient...
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...
High-frequency isolated DC-DC converters are gaining momentum in applications where the demand of isolation matches with that one of compact and light equipment. A seminal topology, constituted by two bridges operating at high frequency and coupled by a transformer, has emerged as an attractive solution that fulfills the above-mentioned demands. The two most popular versions of such a topology are...
Isolated converters are desirable in the DC-DC power conversion applications where isolation and/or a large voltage step-up gain is needed. Traditional isolated DC-DC converters either utilize many switches to achieve high efficiency or use few switches which result in low efficiency. This paper proposes a new single-switch isolated DC-DC converter with a LCL-resonant circuit. The proposed isolated...
