摘要

本文揭示了感应电场对感应功率传输(IPT)系统的影响,提出了一种减小感应电场的方法。感应电场会将电流漏至地面,增加传输垫的功率损耗。因此,引入了电垫中的杂散电容和电垫的等效电路模型,分析了感应电场对电垫的影响。然后提出了一种分布式补偿线圈结构来减小感应电场。建立了仿真模型,并对实验样机进行了测试。仿真和实验结果表明,采用该方法可以显著降低焊盘内的感应电场、漏电流和功率损耗。

Study of the Induced Electric Field Effect on Inductive Power Transfer System
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.
