Abstract: An electric machine may include a housing having a front end and a back end where the front end is the primary mechanical coupling end. The electric machine may include a stator and a rotor arranged within the housing and a shaft connected to the rotor. The shaft may extend out of the front end of the housing and the shaft may be configured to be rotationally driven by the rotor or to rotationally drive the rotor. The electric machine may also include an electronic controller configured to control operations of the rotor and stator and the electronic controller may be mounted on the front end of the housing.

Abstract: The present disclosure relates to a system for sourcing and sinking power. The system may have a bi-directional system of electrical components configured for placement in electrical communication with a power source and a load. The bi- directional system may further be configured to source AC and DC power from the power source to the load and sink AC and DC power from the load to the power source. The system may further include a high frequency isolation transformer. In some embodiments, the system may have four input/output channels. The bi-directional system of electrical components may include a line filter configured to reduce harmonic content, a line converter configured for converting between AC power and DC power, a load converter configured for converting between AC power and DC power, and a load filter configured to reduce harmonic content.
