摘要：A control apparatus of a rotary machine controls drive of the rotary machinewith winding groups. The control apparatus includes electric power converters in multiplesystems, a failure detection portion, and a controller. The electric power converter hasswitching elements in an upper arm and a lower arm, and converts direct current power.
The failure detection portion detects a failure of an electric power converter or a failureof a winding group. The controller operates the switching elements and controlselectricity supply. When the failure detection portion detects the failure, the controllerstops output to an electric power converter in a failure system, and the controllerreduces a total number of times of switching per unit time of the switching elements in anormally operating system.
