Comparative analysis of full bridge and half bridge current resonant DC-DC converter

This paper deals with a comparative analysis of full bridge and half bridge current resonant DC-DC converter. The novel current resonant DC-DC converter has been proposed to improve the power efficiency. The full bridge DC-DC converter is suitable for the low input voltage and large input current as in the fuel cell power supply system, and the half bridge one is suitable to the solar cell power supply system, in which the input voltage is relatively high and variation width of the input voltage in large.
