Abstract

In a power semiconductor module, a first conductive layer including first to fourth electrodes are formed on one of principal surfaces of an insulating layer, and a conductive substrate functioning as a second conductive layer is formed on the other one of principal surfaces. Current paths are switched by controlling switching of a first transistor and a second transistor disposed on a surface of the first conductive layer thereby performing a power conversion. A capacitor is connected, in a region, between the first electrode and the second electrode. When a current flows in the region through the second conductive layer, a charging/discharging current occurs in the capacitor, which results in magnetic field cancellation.
