Title: ROTATING ELECTRIC MACHINE CONTROL DEVICE
Abstract:
A rotating electric machine control device (200) is provided with an inverter (22), a calculation device (24) for controlling turning on/off of switches of the inverter, and an interrupt circuit (30) for forcibly interrupting the switches when an abnormality occurs. The calculation device and the interrupt circuit separately receive the voltage of a power supply and are separately reset in association with lowering of the voltage of the power supply. The interrupt circuit outputs an operation signal indicating a normal operation after a start-up switch is turned on. The calculation device performs, as start-up processing, processing for confirming the input of the operation signal after the start-up switch is turned on. The rotating electric machine control device is equipped with a storage device (60) into which the input history of the operation signal is stored after the start-up switch is turned on. The calculation device performs the start-up processing on the basis of the input history of the operation signal stored in the storage device.
