COMMON MODE NOISE CANCELLING ELECTRIC MOTOR SYSTEM
This abstract first appeared for US patent application 20240413777 titled 'COMMON MODE NOISE CANCELLING ELECTRIC MOTOR SYSTEM
Original Abstract Submitted
an electric motor configuration includes a dual output multilevel inverter. the inverter includes a first and second set of alternating current (ac) phase outputs. the first set of ac phase outputs provide a current, each phase output of the first set of ac phase outputs corresponds to a phase output of the second set of ac phase outputs, and each phase output of the first set of ac phase outputs is offset from the corresponding phase output of the second set of phase outputs by 180 degrees. an electric motor includes a first and second set of antiparallel motor windings. the first set of motor windings is connected to the first set of ac phase outputs and the second set of motor windings are connected to the second set of ac phase outputs. the electric motor includes a mechanical rotation output.
