摘要：
This paper reveals the induced electric field effect on the inductive power transfer (IPT) system and proposes a reduction method for the induced electric field. The induced electric field can leak current to the ground and increase the power loss in the transmission pad. Therefore, the stray capacitance in the pad and the equivalent circuit model of the pad are introduced to analyze the effect of the induced electric field on the pad. Then a distributed compensated coil structure is proposed to reduce the induced electric field. Simulation models are built-in HFSS, and an experimental prototype is built and tested. The simulation and experimental results show that the induced electric field in the pads, the leakage current, and the power loss can be significantly reduced by using the proposed method.
