Abstract
A power module includes a housing with an interior chamber and multiple switch modules mounted within the interior chamber of the housing. The switch modules are interconnected and configured to facilitate switching power to a load. Each one of the switch modules includes at least one transistor and at least one diode. The at least one transistor and the at least one diode may be formed from a wide band-gap material system, such as silicon carbide (SiC), thereby allowing the power module to operate at high frequencies with lower switching losses when compared to conventional power modules.
