Abstract

In order to improve motion control performance of electric vehicles (EVs), In-Wheel Motor (IWM) is the most preferred electric motor arrangement. Our research group has proposed Wireless In-Wheel Motor (W-IWM) concept to solve some technical problems of an IWM, which are reliability and safety issues of power and signal wires. In this research, we did a stability analysis of Series-Series compensated wireless power transfer via magnetic resonance coupling with constant power load. Analysis result is verified by circuit simulation. Also, we propose a load voltage control method using a secondary converter. The effectiveness of the proposed control method has been verified by simulation and experiment using small power test equipment.
