Simulation of Electric Vehicle Inductive Charging Systems

With the development of the electric vehicle, the demand for fast, reliable, safe and fully automated charging is increasing. Inductive charging is regarded an alternative to plugin charging. One problem with inductive charging is that the system is high frequency but only operates around the resonance frequency, at which point the voltage coupling and current coupling are relatively high. However the power factor is still low. The series-series compensation circuit is analyzed. This paper proposed a cascaded multilevel inverter for an inductive charging system which could reduce the voltage and current requirement for individual converter components. Simulation results will be shown for the proposed transfer system.
