Abstract
A power conversion device includes power conversion units connected to a shared power source. The power conversion units each include a contactor, a power converter, and a unit controller. A contactor controller closes or opens the contactor. A sensor measures a value of at least one of input current or output current of the power converter. The unit controller determines presence or absence of a failure of the power conversion units based on the measured value of the sensor, and sends a determination result to another unit controller.
