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.

Abstract: A permanent magnet machine may include a stator a rotor in concentric arrangement with the stator and configured for rotation relative to the stator, the rotor having a plurality of protruding magnets arranged thereon, wherein, the protruding magnets provide for a more lightweight machine with a lower moment of inertia.
