Abstract

Wireless power transfer technology which doesn’t require connector joint has been developed as charging of plug-in hybrid vehicles (PHVs) and an electric vehicles (EVs).
On the other hand, regulation reconsideration and standardization also develop, and the environment for the practical use is being also maintained.
A prototype of the stationary wireless power transfer system and dynamic wireless power transfer system were designed and built. The performance of the both systems were examined. This article reports on design considerations of the both systems and test results of the prototype, including analysis results by JMAG.
