Wireless power transfer (WPT) system for electric vehicle
(EV) charging typically consists of the power converters and
a pair of two magnetically coupled loop coils with a relatively
large air gap from 100 mm to 200 mm in-between [1]–
[3]. Since the required power can be transferred without
any physical contact via the time-varying magnetic field, the
WPT technology enables safe and automated battery charging
process regardless of the weather conditions.
