MULTI-LEVELED PHASE SHIFTED ELECTRIC MACHINE SYSTEM
摘要
A system may include a drive driving a machine. The machine may include a stator having different winding locations distributed evenly across its surface, and a number of coils arranged symmetrically among the winding locations and connected to form N sets of multiple (M) phase windings. For each winding, each corresponding coil may span a single pole to form a full pitch winding. Each winding may be offset with respect to each other to reduce a harmonic content of a magnetic flux within certain frequency range during operation. The drive may include a processing stage that includes N independent modules corresponding to each winding. Each of the N modules may have M output ports for connection to each corresponding winding. Each of the N modules may be powered by a direct current power source, and have an M number of switch matrices that have at least three levels of output.
