Topology Comparison of Primary and Secondary Stages of LLC Resonant Converters for Multi-Purpose Mobility Applications
With the increasing demand for high-power and high-efficiency power conversion systems, LLC resonant converters, which achieve both high efficiency and high power density through soft-switching operation, have attracted significant attention. Accordingly, various topologies based on LLC resonant converters have been proposed; however, studies on topology analysis and selection criteria remain insufficient. Therefore, this paper analyzes device losses, voltage and current stresses, and efficiency characteristics under different output power levels based on PSIM simulations, and proposes a topology selection methodology for the primary- and secondary-side structures of LLC resonant converters.
