Document Type and Number:
WIPO Patent Application WO/2017/199643
Kind Code:
A1
Abstract:
The purpose of the present invention is to perform diagnosis on a current sensor while maintaining high reliability. The inverter control device 16 pertaining to the present invention controls an inverter circuit 9 such that an estimated direct-current current value Idce1 is calculated on the basis of duty values Du, Dv, Dw and alternating-current sensor values Ius, Ivs, Iws output by alternating-current sensors 14a, 14b, 14c, and a diagnosis is performed on a direct-current current sensor 12 on the basis of the estimated direct-current current value and a direct-current current sensor value Idcs output by the direct-current current sensor.
