Dual-bridge DC-DC converter: a new topology of no deadtime DC-DC converters

Two new topologies characterized by no deadtime and small valued output inductor, the dual-bridge DC-DC converter and the dual-bridge converter with ZVS, are presented and analyzed. Simple self-driven synchronous rectification can be used in the new topology for high efficiency implementation. Prototype DC-DC power converters have been tested for verification of the principles. Both simulations and experiments verify the feasibility and advantages of the new topologies.
