Abstract
A control device that controls an inverter interposed between a DC power source and an AC rotary electric machine to perform power conversion between DC power and AC power, wherein the inverter includes a plurality of sets of an upper switching element and a lower switching element connected in series with each other between positive and negative electrodes on the DC side and controlled so as to be turned on and off in a complementary manner; and the control device executes short-circuiting processing, in which all the upper switching elements or all the lower switching elements are controlled so as to be turned on, while the AC rotary electric machine is stationary.
