  • INVERTER CONTROL DEVICE AND ELECTRIC VEHICLE SYSTEM
    Publication number: 20230035063
    Abstract: A deviation between a detection result of an output current of an inverter and an actual current is suppressed. A current detection unit 7 detects a three-phase AC current output from an inverter 3 or input to the inverter 3. An inverter control device 1 controls the inverter 3 based on a current detection value based on a detection result of the three-phase AC current by the current detection unit 7 and a predetermined current command value. The inverter control device 1 corrects the current detection value so as to correct a detection error of the three-phase AC current generated due to a delay time of a filter 72 which is a filter element provided in the current detection unit 7.
