PROBLEM TO BE SOLVED: To provide a matrix converter, which can simplify a circuit configuration of a control system without performing ripple operation, operation about carrier amplitude modulation, etc. , and to provide a control method for a matrix converter. SOLUTION: A line voltage control command signal generator 11 generates an output voltage command signal for outputting a specified three-phase AC output voltage, and a current flow rate generator 12 generates a signal which shows the flow rate, based on a specified input current command signal. A command signal operating part 13 corrects the output voltage command, based on the output voltage command signal generated by the line voltage control command signal generator 11 and the signal which shows the current flow rate generated by the current flow rate generator 12. PWM conversion signal generators (15 and 17) generate PWM conversion signals, based on the corrected output voltage command signal and the carrier signal. A conversion part converts the three-phase input voltage into specified three-phase AC output voltage, by the generated PWM conversion signal. COPYRIGHT: (C)2008,JPO&INPIT
