Title:
電流センサの診断装置
Document Type and Number:
Japanese Patent JP6958170
Kind Code:
B2
Abstract:
A diagnostic device for a current sensor disclosed herein may include an AC power calculation unit, a DC power calculation unit, and a determination unit. The AC power calculation unit may be configured to calculate AC power outputted from the inverter based on a measurement value measured by the current sensor. The DC power calculation unit may be configured to calculate DC power outputted from a DC power source that supplies power to the inverter. The determination unit may be configured to output a signal for notifying occurrence of an abnormality of the current sensor in a case where a difference between the calculated AC power and the calculated DC power is larger than a predetermined threshold.
