Abstract

As the wireless power transfer(WPT)system based on the conventional LC resonant topology can not realize constant-current power supply to load when it is varied dynamically and bypass the problem of system operating frequency detuning

a WPT system with a novel composite resonant network is proposed in which the primary side is LCL resonant topology and the secondary side is LCC resonant topology. Firstly

the equivalent circuit of the magnetic circuit agencies is established according to the leakage inductance model

and equations of the resonant frequency and the output current are obtained. Then

the requirements of constant-current power supply and stable operating frequency of WPT system are obtained by system parameter optimization. Finally

the simulation results verify that the parameter optimization based WPT system with the novel composite resonant network is able to realize constant-current power supply and stable operating frequency. The experimental results show the correctness and effectiveness of the theoretical and simulation analysis.
