Research and Development for Industrial Application of Inductive Wireless Power Transfer

Abstract

　Recent research and development activities for industrial application of inductive wireless power transfer are introduced. Rapid wireless charger for heavy duty vehicles, such as electric buses, with several tens or even a hundred kilowatt charging power, has been evaluated by public road operation. Recent wireless charger for automated guided vehicle can supply as large as 115 A at 24 V to reduce charging time and increase operation rate. Drone frustum wireless charging port will provide an easier automated drone operation for various industrial applications in near future.
