Abstract
A power conversion device includes two lower arm switching elements connected in parallel to each other and a lower arm driver circuit that drives the two lower arm switching elements. The two lower arm switching elements respectively include gate terminals and detection terminals used to detect counter-electromotive forces. The power conversion device includes a common connection line that connects the two detection terminals to each other and connects the two detection terminals to an addition circuit of the lower arm driver circuit. A combined electromotive force is transmitted via the common connection line.
