Abstract: In order to solve the problem of frequent charging and short cruising range when electric vehicles adopt the static wireless charging method, a mobile wireless power supply system for electric vehicles is designed and modeled and simulated. Firstly, an inverter circuit with multiple inverters in parallel is designed to meet the high power demand of the power supply system. Secondly, a bilateral LCC compensation topology is adopted, and the calculation and analysis are completed after T-transformation. Finally, a wireless power supply system with two primary windings in parallel and a single primary winding wireless power supply system are designed, and the model building and simulation are completed using MATLAB/Simulink. Simulation analysis shows that, compared with the wireless power supply system with single primary winding, the wireless power supply system with two primary windings in parallel has higher transmission power and efficiency.
