Abstract: Systems and methods associated with example power converter systems are disclosed. For instance, a power converter system can include a power converter couplable to an input power source and configured to generate an output power substantially at a grid frequency. The power converter can include one or more inverter bridge circuits, each associated with an output phase of the power converter. Each inverter bridge circuit can include one or more first switching modules having a pair of switching elements coupled in series with one another, and an output coupled between the pair of switching elements. At least one switching element of each first switching module includes a reverse blocking transistor. The power converter further includes one or more input bridge circuits having a plurality of second switching modules coupled in parallel, each second switching module comprising a pair of silicon carbide transistors.
