PROBLEM TO BE SOLVED: To provide a control circuit for a matrix converter circuit that performs processing that is the same as processing, by which, after rotation coordinate conversion is performed, predetermined control is performed and static coordinate conversion is performed on a generated correction value signal, and has linearity and time invariability.SOLUTION: Correction value signals are generated by performing signal processing on each deviation signal using a first transfer function at each of a virtual converter control part 5' and a virtual inverter control part 6', a PWM signal is generated based on three correction value signals obtained by two-phase/three-phase converting two correction value signals, and a PWM signal for controlling a matrix converter circuit is generated by synthesizing the PWM signal generated by the virtual converter control part 5' and the PWM signal generated by the virtual inverter control part 6' with each other, wherein when a transfer function expressing predetermined control processing is referred to as F(s), the first transfer function is G(s)=[F(s+jω)+F(s-jω)}/2. |
