Saturable reactor assisted soft-switching full-bridge DC-DC power convertors

IEE Proceedings B Electric Power Applications, 1991
A new soft-switching converter technique is introduced which employs small saturable reactors and phase-shift modulation. This considerably reduces switching losses with no substantial increase in conduction losses. The proposed soft-switching concept and its modifications to full-bridge DC-DC power convertors are shown and discussed.

Class E2 resonant DC/DC power convertor

IEE Proceedings G Circuits, Devices and Systems, 1990
A new high-frequency high-efficiency resonant DC/DC convertor is introduced. It is composed of a Class E inverter and a Class E rectifier. The convertor operates with load resistances ranging from a full load to infinity. It can regulate the output voltage by varying the switching frequency over a narrow range, owing to a high value of the loaded ...

High power IGBT-based DC/DC converter with DC fault tolerance

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
This paper studies a DC/DC converter based on IGBT-bridges which is suitable for connection to HVDC (High Voltage DC) and for building high power DC grids. The DC faults are of highest concern for DC grids, and the primary converter design aims are to achieve inherent current regulation under DC faults in addition to minimizing converter losses. Design
