摘要

无线电力传输(WPT)技术是一种很有前途的方法,可以方便地为电动汽车和插电式混合动力汽车的电池充电。采用磁耦合的WPT系统会产生一个周围磁场,从电磁兼容的角度来看,有利于减小该磁场。我们提出了一种利用磁场抵消线圈和导电板来减少磁场的方法。该方法可以在不降低耦合系数的情况下减小距离WPT系统较远的磁场。

Magnetic field canceling coil for wireless power transfer system
Wireless power transfer (WPT) technology is a promising approach to easily charging the batteries of electric vehicles and plug-in hybrid vehicles. WPT systems that use magnetic coupling generate a surrounding magnetic field, and it is beneficial to reduce this magnetic field from the viewpoint of electromagnetic compatibility. We propose a magnetic field reduction method using magnetic field canceling coils and conductive plates. This method can reduce the magnetic field far from the WPT system without reducing the coupling factor.
