A review of multi-elements resonant converters topologies

The paper deals with a review of multi-elements resonant converter topologies. The superior performance of the proposed resonant converter provides inherent current protection and very low circulating energy. The proposed resonant converters can operate with a short output circuit. The converter can achieve zero current swathing (ZCS) and zero voltage switching (ZVS)conditions for the primary and secondary-side of the device respectively. The converters achieve 91W/in
³
power density and efficiency up to 96% at the full load. The paper includes the basic equations, analysis and simulation of chosen topologies (LCTLC, LCLCL, LCL2C2).
