Abstract
An object of the present invention is to increase the reliability of a power module and a power converter and to extend their life. In order to achieve this, a power module includes: two switching devices each including a diode and a transistor, the two switching devices being electrically connected in parallel; and an insulating substrate on which the two switching devices are mounted. Further, a gate electrode of MOFET that each of the two switching device has is electrically connected to a gate resistance. Further, of the two switching devices, the gate resistance that is electrically connected to the switching device, whose current value is smaller when a predetermined voltage is applied in the forward direction of the body diode, is greater than the gate resistance that is electrically connected to the switching device whose current value is larger.
