三相–単相マトリックスコンバータを用いた非接触給電システムの電力伝送制御

This paper presents the power flow control in wireless power supply systems using a matrix converter that directly converts from three-phase AC voltage to high-frequency AC voltage. The operation principle and control method that achieve stable power transmission on the secondary side and reduction of current distortion in three-phase AC current are explained. In addition, the switching patterns and duty ratios of the six bidirectional switches of the primary side matrix converter are clarified, and the effectiveness of the proposed control method is experimentally verified using 2kW prototype system.
