Abstract
The objective of this study is to transfer multiphase power wirelessly in a simple system using frequency modulation (FM) technique. With the progress of wireless power transfer (WPT), research works are conducted to transfer power to motors wirelessly, such as application in in-wheel motors and articulated arm robots. For three-phase motors, multi-phase WPT is required. In conventional systems, the receiver of a multi-phase WPT system tends to be large because a complex circuit and large capacitor are mounted on the receiver. In this research, the aim is to reduce the size and weight of the receiver by adopting FM technique. The proposed circuit has a simple structure with a small number of components, and effective multi-phase wireless power transfer is verified through simulation and experiments.
