A novel square-wave converter with bidirectional power flow [PDF]
Proceedings of the IEEE 1999 International Conference on Power Electronics and Drive Systems. PEDS'99 (Cat. No.99TH8475), 1999 A novel ZVS phase-shift controlled bidirectional DC-DC convertor is proposed. It possesses the conventional features of phase-shifted convertors, including constant switching frequency, zero-voltage switching (ZVS) and voltage control by phase-shift. However, the new convertor has been improved by developing a bi-directional power flow capability and ...

Highly Efficient High-Voltage MOSFET Converter with Bidirectional Power Flow Legs [PDF]
Journal of Power Electronics, 2014 In terms of power loss, a MOSFET has two advantages over an IGBT with an antiparallel diode: purely resistive without an offset voltage in conduction and no tail current at turn-off. However, the reverse recovery characteristic of the body diode is so poor that MOSFETs have not yet been available for high-voltage power converters with bidirectional ...
