Abstract: For reaching the electric vehicle on-board wireless charging regulations, the dual inductor-capacitor-inductor (LCL) resonant compensation network is analysed, and a dual LCL variable compensation parameter magnetically coupled resonant wireless charging system software is clearly proposed. Firstly, we use the primary and secondary side models of two-port network system to obtain the dual LCL mathematical analysis model, and analyse the completion of the constant current or constant voltage output parameter configuration criteria; then, we design the scheme variable compensation parameter circuit structure according to the constant current and constant voltage parameter configuration characteristics; then, we design the parameter configuration to promote the magnetically coupled resonant wireless charging according to the interrelationship between the important main parameters and the system transmission characteristics. Finally, the experimental platform is constructed, and the voltage or flow rate derived from the certified customised system software is relatively small and can meet the constant voltage and constant current charging regulations.

Keywords: dual LCL; resonance compensation; electric vehicles; wireless energy transmission; constant voltage; wireless charging; experimental platform.
