Abstract

The present invention provides a wireless soft-switching in-wheel motor drive system and a method for realizing the same. The method comprises pre-misaligning the primary winding and the secondary winding of a magnetic coupler of the in-wheel motor drive system for an angular offset such that an input impedance of the resonant compensation network of the in-wheel motor drive system has a short-circuit boundary frequency less than an open-circuit boundary frequency throughout a target misalignment tolerance between the primary winding and the secondary winding. The present invention can ensure soft switching of the in-wheel motor drive system, save system volume, minimize power losses, and achieve high efficiency.
