| Research Abstract |
An ac to ac power converter is used for the variable-speed ac-motor drive system. Matrix converters are developed for ac to ac power converters with high efficiency and high power density in the next generation. However, the general PWM control scheme for controlling the output voltage and the input current of the matrix converter has not established. In this study, the general PWM control scheme for three circuit configurations of the matrix converters has been derived using the reduction control of the number of commutations and the evaluation method of the output voltage harmonics. The control characteristics in experiments are shown.
