预期无线电力传输（WPT）可以是布线困难的电力馈送方法。通过磁共振耦合，功率传输距离可达数米。它比传统的感应法传输距离要长，但电磁场对生物体和通讯的影响值得关注。屏蔽天线以减少EMF泄漏与长发射距离相冲突。本文研究了对称N相WPT系统作为WPT中的电动势泄漏抑制。理论分析和仿真结果表明，该方法具有约-20 dB的泄漏抑制能力，实验结果表明，该方法具有约-10 dB的泄漏抑制能力。
It is expected that Wireless Power Transfer (WPT) can be a power feeding method where wiring is difficult. The power transmitting distance is up to a few meter via Magnetic Resonance Coupling. It is longer than the transmitting distance via conventional induction method, However, effects of Electromagnetic Field (EMF) on organism and communication should be concerned. Shielding the antennas for EMF leakage reduction conflicts long transmitting distance. In this paper, we investigated symmetric N-phase WPT system as EMF leakage suppression in WPT. We showed that the proposal method has about -20 dB EMF leakage suppression ability in theory and simulation, and about -10 dB EMF leakage suppression ability in experiment.
