Abstract
Provided is a power conversion device capable of continuing the transmission of power even in the event of failure of a DC-to-DC converter cell. The power conversion device according to the present invention includes: a unit having a plurality of DC-to-DC converter cells; a short-circuit device that short-circuits a failed cell; and a control circuit that controls the plurality of DC-to-DC converter cells. The control circuit controls the voltage of a second cell terminal of a healthy cell included in a unit that includes the failed cell, based on a failed cell count m, so that the power of a first cell terminal and the power of the second cell terminal are matched.
