Abstract

This paper deals with a novel composite resonance DC-DC converter for low input voltage, large input current and high output voltage with the voltage doubler rectifier, which is developed to apply to the power conditioner of the fuel system. The proposed DC-DC converter has the current and voltage resonance functions to reduce the switching power loss. The primary and secondary sides of the converter are composed of the current resonant full bridge circuit, and voltage doubler, respectively. For this reason, the high power efficiency of this converter can be realized under the condition of a low input voltage, large input current and high output voltage.
