要約(英語): The fundamental analysis of power supply and rectifiers used for wireless power transfer with magnetic resonant coupling (MRC) is discussed in this paper. The MRC enables an efficient wireless power transfer over middle-range transfer distances. MRC for wireless power transfer is desired to operate at high frequency in the industry science medical (ISM) band, such as 13.56MHz, because the size of the transfer device decreases with increasing transfer frequency. Therefore, the output frequency of the power supply on the transmitting side should be 13.56MHz. In addition, the rectifier on the receiving side is operated with a high efficiency.This paper focuses on the reflected power on the power supply and rectifiers. Thus, the parametric design method is clarified with power supply including a low-frequency pass filter (LPF) to match the output, impedance of the power supply with the characteristic impedance of the transmission line. In addition, the effects due to the rectifiers with SiC and GaN diodes are confirmed by performing an experiment and a loss analysis.
