Design of a 100W bi-directional LCC series-parallel resonant DC-DC converter

This paper presents the design of a 100 W bidirectional LCC series-parallel resonant converter. The design incorporates a ratio transformer to segregate between low- and high-current devices. Not only does the transformer segregate it also supports the parallel capacitor at its terminal primary side for boost/buck operations. The converter is built on RF4 material and experiments have been conducted to verify the design.
