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： Aboard main body part (10) has a multilayer structure (4) with even-numbered layers including a first layer (41) formed on a surface part (10a) on one side (Z1) and a second layer (42) formed on a surface part (10a) on the other side (Z2). On both of the first layer (41) and the second layer (42), a low voltage region in which a low voltage circuit is disposed, a high voltage region in which high voltage circuits are disposed, and an insulating region (E) in which the low voltage region is electrically isolated from the high voltage region are formed. At least a part of a first high voltage circuit is disposed in a first-layer high voltage region formed on the first layer (41), and at least a part of a second high voltage circuit is disposed in a second-layer high voltage region formed on the second layer (42).
