Research on Wireless Charging System Based on Bilateral LCC

The soft switch of bilateral LCC wireless charging system is affected by network parameters. A topological parameter optimization method based on bilateral LCC wireless charging system is proposed in this paper. Equivalent circuit model of bilateral LCC wireless charging system were analyzed, and the expressions of output current and equivalent impedance are derived. Then, the changing trend of capacitor element parameters on system phase difference is studied, and the key method to optimize capacitance is given. Finally, an experimental prototype with a working frequency of 85KHz and an output power of 2KW is built for experiment to verify the effectiveness of the parameter optimization design scheme.
