A DC voltage value from a DC voltage detection unit (201) is directly inputted to a voltage correction unit (202) without using a compensator or a filter. Accordingly, a voltage correction unit (202) can rapidly perform a correction process even upon a sudden voltage change such as an instantaneous power supply stop, an instantaneous voltage lowering, or a recovery from an instantaneous voltage lowering. Moreover, since a limit unit (212) limits a link resonance compensation amount to a predetermined range, it is possible to prevent an excessive fluctuation of a link resonance compensation amount upon a sudden voltage change. Moreover, the link resonance compensation amount limited to the predetermined range by the limit unit (212) is inputted to a compensator (206) of an appropriate control band in control calculation units (204 - 208). Accordingly, it is possible to avoid response of a higher speed than is necessary and perform stable control.
