  • Patent number: 8519656
    Abstract: A synchronous machine starting device in which AC power is supplied to an armature of a synchronous machine, the supplied AC voltage is detected to determine a rotor position of the synchronous machine, and the supplied power is controlled based on the detected rotor position. To detect rotor position, a first position signal indicating a timing at which a level of AC voltage supplied to the armature of the synchronous machine reaches a prescribed value is output. An error of an estimated phase is calculated based on the estimated phase indicating the rotor position and the detected AC voltage, and the estimated phase is calculated based on the calculated error to produce a second position signal indicating the calculated estimated phase. A selected of first and second position signals is output to indicate the rotor position of the synchronous machine for control of AC power supplied to the armature.
