An Overmodulation drive for a dual winding motor is proposed in this paper. Our Proposed overmodulation drive counterbalances the high harmonic component in an overmodulation drive by compensating the modulation signal of the one of the windings by the other one in a dual winding motor. As the electrical angles of the modulation signal peak in the two windings are different in a dual winding motor, the high harmonic component in one of the windings can be compensated by the other one in a dual winding motor. With our proposed overmodulation drive, the amplitude of the basic voltage increased by 3.5%. Our proposed overmodulation drive is analyzed and the experiment results are confirmed.
