Abstract
A power conversion device includes first and second power semiconductor elements, and a circuit for transferring a drive signal of the first and second power semiconductor elements. The circuit board includes a first emitter wire which is formed along an arranging direction of the first power semiconductor element and the second power semiconductor element, a first gate wire which is disposed between the first power semiconductor element and the first emitter wire, a second gate wire which is disposed between the second power semiconductor element and the emitter wire, a third gate wire which is disposed to face the first gate wire and the second gate wire with the emitter wire interposed between the third gate wire and the first gate wire and the second gate wire, and a first gate resistor which connects the first gate wire and the third gate wire over the first emitter wire.
