Usually, topologies like SS, LCL-LCL, and LCC-LCC, are preferred for Bidirectional(BiWPT) WPT due to their symmetrical primary and secondary side compensation structures. All these topologies also have load-independent resonance. However, the inverter current in LCL and LCC-based topologies contain harmonics which leads to the higher VA loading on the inverter. Also, due to higher peak current, the required tank inductor size becomes larger. This paper reports the conventional designs of SS, LCL-LCL and LCC-LCC compensated WPTs which can provide only constant current (CC) output. This paper proposes the constant voltage (CV) mode of design of LCL topology with a novel design that ensures significantly lower harmonics in the inverter output current. Also, a comparative study based on the harmonic content in the inverter current of different BiWPT compensation topologies under CC and CV modes of design, is included the show the superior performance of the proposed design for V2G application.
