Abstract: Power converters for use in energy systems are included. For instance, an energy system can include an input power source configured to provide a low voltage direct current power. The energy system can include a power converter configured to convert the low voltage direct current power provided by the input power source to a medium voltage multiphase alternating current output power suitable for provision to an alternating current power system. The power converter can include a plurality conversion modules. Each conversion module includes a plurality of bridge circuits. Each bridge circuit includes a plurality of silicon carbide switching devices coupled in series. Each conversion module is configured to provide a single phase of the medium voltage multiphase alternating current output power on a line bus of the energy system.
