Abstract
A control apparatus is provided for controlling drive of a rotating electric machine that has coils of two or more phases. The control apparatus includes a first inverter to be connected with first ends of the coils, a second inverter to be connected with second ends of the coils, and a controller. The first inverter has a plurality of first switching elements each corresponding to one of the coils. The second inverter has a plurality of second switching elements each corresponding to one of the coils. The controller includes a first operation circuit configured to generate a first control signal for control of the first inverter and a second operation circuit configured to generate a second control signal for control of the second inverter. Moreover, the control apparatus is configured so that switching timings are synchronized, based on synchronization information, between the first and second inverters.
