Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/079299
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a power conversion device with which a diagnosis of a voltage detector can be performed at a low cost. This power conversion device is equipped with: a control circuit that drives an inverter; a power supply circuit 11b that has a transistor S0 and that converts input voltage of an inverter and outputs a voltage that is applied to the control circuit; and a microcontroller 9a that, on the basis of the switching frequency and the on-time for a switching signal that is input to the transistor S0 of the power supply circuit 11b, performs a diagnosis on a DC input voltage detector 4 that detects the input voltage.
