Patent ID: 7710081

Claim:
An energy processing system comprising: an electric machine that comprises: a stator with a plurality of winding locations distributed substantially evenly across a surface of the stator; and a plurality of conductors formed into a plurality of coils arranged substantially symmetrically among the plurality of winding locations and connected to form a number (N) of sets of multiple (M) phase windings, wherein for each of the windings, each of the coils spans a single pole to form a full pitch winding, and wherein each of the N sets of windings are substantially offset with respect to each other so as to substantially reduce a harmonic content of a magnetic flux within a first frequency range during operation; and a processing stage that comprises N substantially independent modules corresponding to each of the N sets of windings, each of the N modules having M input ports for connection to each of the corresponding M windings, and having a first and a second output port, wherein the first and second outputs ports for each of the N modules are connectable to a first node and a second node of a voltage bus.
