要約(英語): This paper presents an induction heating system using a matrix converter. The proposed circuit consists of a three-phase AC to high-frequency single-phase AC converter, two high-frequency transformers, and a heating coil. Because the power conversion number of the proposed system is one and SiC MOSFETs are used for switching, a downsized and highly efficient system is achieved. In an induction heating device, it is inevitable that the heating coil be replaced according to the heating object. However, this specification causes power supply current distortion. By controlling the matrix converter, both the downsizing and high efficiency of the system, as well as the specifications of the heating device are realized. Therefore, in this study, the authors propose a circuit configuration and its control method at the rated output frequency or less for an induction heating system using a matrix converter. In addition, the authors propose the derivation method of the duty cycle to suppress the source current harmonics. The effectiveness of the proposed system is verified by experiments.
