<P>PROBLEM TO BE SOLVED: To provide a motor driving inverter control device that satisfies even the harmonic regulation of an AC power supply current while being achieved in the reduction of a size, weight and cost. <P>SOLUTION: The motor driving inverter device is equipped with a small-capacity capacitor 12 between an extremely small-capacity reactor 11 and a DC bus bar of an inverter 3. The motor driving inverter device can cope with the harmonic regulation of the AC power supply current by operating a dead-time compensation voltage that compensates a distortion voltage caused by the dead time of the inverter; is achieved in the reduction of the size, weight and cost; and furthermore, can suppress a harmonic component of the AC power supply current, thus improving the reliability of a system. <P>COPYRIGHT: (C)2007,JPO&INPIT |
