摘要：A control apparatus for an AC rotary machine includes voltage application units3, 4 for applying voltages respectively to two sets of three-phase windings of AC rotarymachine 1, control unit 5 that outputs voltage commands to the voltage application units3, 4, and fault detection units 6, 7 that output fault detection signals when a ground shortfault or a power short fault occurs in the three-phase windings, the fault detectionsignals varying in accordance with the ground short fault and the power short fault. Afterdetermining on the basis of the fault detection signal that a ground short fault hasoccurred, control unit 5 outputs a voltage command to voltage application unit 3, 4related to the faulty set in order to set voltages of respective phases of the three-phasewindings at a negative electrode side potential V- of DC power supply 2, and afterdetermining that a power short fault has occurred, control unit 5 outputs a voltagecommand to voltage application unit 3, 4 related to the faulty set in order to set thevoltages of the respective phases of the three-phase windings at a positive electrodeside potential V+ of DC power supply 2.
