Efficiency Optimization Method of BIPT System with Asymmetrical Double-Sided LCC Compensation Network

Bidirectional Inductive Power Transfer (BIPT) system can realize the bidirectional flow of electric energy between the power grid and electric vehicles, and has broad application prospects. The double-sided LCC compensation network has the advantages of constant current output and insensitivity to contactless transformer offset, and is widely used in the field of bidirectional wireless charging of electric vehicles. The existing BIPT systems based on double-sided LCC compensation network are designed with double-sided LCC compensation network with symmetrical parameters, but the parameters of LCC compensation network in the actual system will be asymmetrical, resulting in the decrease of system power and efficiency. In order to solve the above problems, the asymmetric double-sided LCC compensation network of two-way radio energy transmission system is studied in this paper with the goal of efficiency optimization under the premise of the asymmetric inductance.
