DC TO DC CONVERTER

WIPO Patent Application WO/2018/148932

A1

Disclosed is a DC to DC converter (1). The DC to DC converter includes a first H-bridge converter circuit, a second H-bridge converter circuit sharing a phase leg with the first H-bridge converter circuit, a first rectifier circuit (12), a second rectifier circuit (14), a first transformer (11) and a second transformer (13). The primary winding of the first transformer is connected to the output terminals of the first H-bridge converter circuit, and the secondary winding of the first transformer is connected to the input terminals of the first rectifier circuit. The primary winding of the second transformer is connected to the output terminals of the second H-bridge converter circuit, and the secondary winding of the second transformer is connected to the input terminals of the second rectifier circuit. One of the output terminals of the first rectifier circuit and one of the output terminals of the second rectifier circuit are connected in series. The first rectifier circuit can compensate an insufficient part of the rated output power to provide the output power to a load. Since the first transformer and the second transformer commonly provide power to the load during a power transmitting period, transformers with smaller power level can be used to implement the first transformer and/or the second transformer, thereby the volume of the DC-DC converter being decreased.
