Abstract

The power transfer efficiency of magnetic resonance coupling wireless power transfer (WPT) system is sensitive to the alignment of the transmitter and receiver. In this paper, a multi-coil WPT structure is proposed to enhance power transfer efficiency. It is shown by experimental results that the proposed WPT system can achieve 90.2% efficiency in aligned working conditions. Meanwhile, this WPT system maintains over 70% efficiency from 0 to 55 mm misalignment distance, which is 66% of the length of the Rx board. The proposed WPT system is suitable for the applications of implant devices for biomedical health care and treatment.
