A control apparatus for a rotary electric machine has a DC-AC converting circuit with high- and low-potential-side switching elements to compose an inverter. In this apparatus, a connecting/disconnecting circuit is arranged to be electrically opened and closed between the DC-AC converting circuit and a power supply. A determining member determines whether or not the high-potential-side and low-potential-side switching elements have a malfunction. A failsafe performing element opens the connecting/disconnecting circuit and turns on both the high-potential-side and low-potential-side switching elements residing in a part of the inverter, when it is determined that there is caused a malfunction in the switching elements. The turned-on high-potential-side and low-potential-side switching elements realizes a short-circuit state therein.
