Abstract
A semiconductor module is provided with a high potential wiring, an output wiring, a low potential wiring, an upper arm switching device, an upper arm diode, a lower arm switching device, and a lower arm diode. A ratio of steady loss to switching loss of the upper arm switching device is configured to be smaller than a ratio of steady loss to switching loss of the lower arm switching device. Further, a ratio of steady loss to switching loss of the upper arm diode is configured to be smaller than a ratio of steady loss to switching loss of the lower arm diode.
