Abstract
A rotary electric machine control apparatus is provided which controls energization of a rotary electric machine having a plurality of winding sets. The apparatus includes an energization control circuit that is provided for each of the winding sets and has a switching element related to switching of energization to the winding set, a driver circuit that outputs a drive signal to the switching element through a signal line connected to the switching element, and a protection element that is connected to the signal line and in parallel with the switching element. When combinations of the winding sets and electronic components including the energization control circuit provided for each of the winding sets are regarded as systems, in at least one of the systems, performance of the protection element is differentiated from that in the other system to make noise resistance different from noise resistance in the other system.
