Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207224
Kind Code:
A1
Abstract:
This power conversion device is provided with: an intermediate capacitor that performs charge/discharge operations; and a voltage sensor that detects the voltage of the intermediate capacitor. The power conversion device is also provided with: a current sensor that detects a current flowing in a reactor; and an abnormality determining unit that determines an abnormality of the voltage sensor using a current value calculated on the basis of a detection value obtained from the current sensor. The power conversion device is capable of detecting a gain abnormality, offset abnormality, and fixing abnormality of the voltage sensor.
