Abstract
In one embodiment, a power cell module includes: a high frequency line converter (HFLC) to receive a phase of input power from a utility source, the HFLC including a first silicon carbide (SiC) stage and a second SiC stage; a transformer having a primary coil coupled to the HFLC and a secondary coil coupled to a high frequency motor converter (HFMC); the HFMC to output a phase of output power to a load, the HFMC including a third SiC stage and a fourth SiC stage; and a two-phase cooling system having conduits that are adapted to provide a flow of cooling media through the HFLC, the transformer and the HFMC.
