Electrolyzer produces hydrogen and oxygen from off-peak electricity generated by the renewable energy sources (wind turbine and photovoltaic array), for later use in the fuel cell to produce on-peak electricity. A power conditioning system, usually a DC-DC converter is required to couple the Electrolyzer to the system bus. This paper presents the design of three soft-switched high-frequency transformer isolated dc-to-dc resonant converters for this application based on the given specifications. Due to the wide variation in input voltage and load current, no converter can maintain zero-voltage switching for the complete operating range. Based on an extensive comparison of all the selected converters, LLC resonant converter will be studied in the future.
