Abstract

See full text

An isolated DC to DC converter including zero voltage switching and a current doubler. Current sensors are located between a positive input of the DC to DC converter and a current doubler is used in an output stage of the DC to DC converter in order to enable more accurate current sensing in a main transformer to prevent saturation of the transformer core and provide increased efficiency and power output with lower electromagnetic noise. The input of the DC to DC converter is isolated from the output of the DC to DC converter, and the DC to DC converter may be used in a hybrid or all-electric vehicle to provide an accessory bus from a power source of the vehicle.
