摘要： A rotary electric machine control apparatus (1) suitably controls two inverters (10) connected to associated ends of open windings (8). The rotary electric machine control apparatus (1) performs target control involving: controlling a first one of the inverters (10), which is selected from a first inverter (11) and a second inverter (12), by rectangular wave control; and controlling a second one of the inverters (10) by special pulse width modulation control that is one type of pulse width modulation control. The special pulse width modulation control is a control method to produce a switching pattern (Su2+) that is based on a difference between a switching pattern resulting from the pulse width modulation control and a switching pattern (Su1+) resulting from the rectangular wave control when a target voltage is to be generated in the open windings (8).

摘要： Two inverters (10) provided at respective both ends of open-end windings (8) are appropriately controlled. As control regions (R) of a rotating electrical machine (80), a first speed region (VR1) and a second speed region (VR2) in which the rotational speed of the rotating electrical machine (80) is higher than in the first speed region (VR1) for the same torque are set, and in the second speed region (VR2), a rotating electrical machine control device (1) controls both inverters (10), a first inverter (11) and a second inverter (12), by mixed pulse width modulation control in which control is performed such that a plurality of pulses with different patterns are outputted during a first period (T1) which is a half cycle of electrical angle, and an inactive state continues during a second period (T2) which is the other half cycle.

摘要： In a first control state, it is determined which one of a first failure pattern (FP1) and a second failure pattern (FP2) is a failure pattern (FT), and in a second control state, it is determined which one of a first lower-stage-side failure pattern (LF1) and a second lower-stage-side failure pattern (LF2) is a lower-stage-side failure pattern (LF), and it is determined which one of a set of upper-stage-side arms of a first inverter (11), a set of lower-stage-side arms of the first inverter (12), a set of upper-stage-side arms of a second inverter (12), and a set of lower-stage-side arms of the second inverter (12) is failure-side arms, based on a result of the determination in the first control state and a result of the determination in the second control state.
