Novel current resonance DC-DC converter with voltage doubler rectifier for fuel cell system

摘要

This paper deals with a novel composite rsonance DC-DC converter for low input voltage, large input current and high output voltsge with the voltage doubler rectifier. which i developed to appl y to the power conditioner of the fuel system. The proposed DC-DC cnverter has the current and voltage resonance fnctions 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 iput current and high output voltage.
