  • Control apparatus for AC rotary machine
    Patent number: 8022660
    Abstract: A control controls starting of an AC rotary machine by calculating a resistance drop component, corresponding to a resistance drop of the AC rotary machine, based on a detection current, and adjusts angular frequency of an AC output voltage based on subtracting the resistance drop component from a voltage command, and, simultaneously, adjusting amplitude of the AC output voltage so that amplitude of an AC phase current may change in conformity with a predetermined function.
    Type: Grant
    Filed: June 29, 2006
    Date of Patent: September 20, 2011
    Assignee: Mitsubishi Electric Corporation
    Inventors: Yoshihiko Kinpara, Masaki Kono, Kiyoshi Eguchi, Keita Hatanaka, Mitsuo Kashima, Kouichi Arisawa
