Dual Transmitter Coils Wireless Power Transfer System With Improved Energy Saving Technique

This paper presents a dual transmitter coils wireless power transfer (WPT) system. The proposed WPT system uses two independent transmitter coils to operate simultaneously and adopts an optimized energy saving technique. In addition, the proposed WPT system transmits the energy of the transmitter coils in multiple directions to the receiver coil. The prototype implements dual transmitter coils and a single receiver coil. The experimental results verify that the receiver coil exhibits good energy transfer performance, directly or horizontally, under the same resonance frequency.
