Abstract :
Recently, the isolated high frequency boost DC/DC converter has been used widely for PCS (Power Conditioning System) because of the requirements of small size and low cost. However, the high frequency isolated boost DC/DC converters applied the conventional voltage-fed converter and current-fed converter have some problems like high conduction losses and high surge voltage due to high circulating current and leakage inductance, respectively. To improve these problems, a novel secondary LLC (called SLLC) series resonant converter is proposed in this paper and its theoretical analysis, simulation and experimental results for a boost DC/DC converter using SLLC series resonant topology verifies the proposed topology. 1kW experimental prototype is designed and tested.
