Title: CONTROL DEVICE FOR ROTATING ELECTRICAL MACHINE
Abstract:
A rotating electrical machine unit (16) is provided with: a rotating electrical machine (21) having an armature winding (25) and a field winding (26); and a field circuit (23) for energizing the field winding according to whether a plurality of switching elements (51-54) are on or off. The field circuit is provided with the field winding in a parallel path unit that is connected to both ends of a second switching element of the ground side among the switching elements (51, 52), and is parallel to that second switching element, and the switching elements respectively undergo on-off control by duty signals so as to be on in reciprocal periods. A control device for a rotating electrical machine (24) is provided with: an acquisition unit for acquiring the current detection value for energizing current that flows to the field circuit; an abnormality diagnosis unit for implementing an abnormality diagnosis of the field circuit on the basis of the duty signal and the current detection value; and a fail-safe processing unit for implementing designated fail-safe processing when there is a diagnosis by the abnormality diagnosis unit to the effect that an abnormality has occurred.
