N2 - In this paper, an electric vehicle wireless charging technology based on switch-controlled capacitor (SCC) under the three-phase-shift (TPS) control strategy is proposed. Due to the existence of non-negligible harmonics in LCC-LCC compensation wireless power transfer (WPT) systems, a time domain model based on fundamental harmonic approximation (FHA) taking higher harmonics into account is proposed. In order to improve the efficiency of LCC-LCC compensation topology, the load matching is analyzed. Furthermore, the primary side of the series compensation capacitor is designed to use the SCC technology, which effectively lowers the inverter's output current by ensuring that all MOSFETs realize ZVS. Finally, a simulation model is built on MATLAB/Simulink to verify the effectiveness of the proposed strategy.
