Abstract
In a converter circuit of an electric power conversion device, an adjustment portion divides a voltage of a battery input to a semiconductor module, by a first capacity element and a second capacity element that are connected in series to each other. Then, a middle point between the first capacity element and the second capacity element is connected to a cooler to fix a potential thereof. The electric power conversion device can ensure that a waveform of a surge voltage that is generated on a creepage surface between a lead frame terminal and the cooler has a negative voltage range (a range where an offset voltage is applied).
