Abstract
A system may be provided that may include an integrated motor drive configured to couple to a motor. The integrated motor drive may include a first converter that may be configured to electrically couple with a winding assembly of the motor. The first converter may include at least first conversion circuitry configured to form a first electrical excitation waveform and second conversion circuitry coupled in parallel to the second conversion circuitry and configured to form a second electrical excitation waveform. The first converter may also include a first transformer configured to form a first summation electrical excitation waveform from the first electrical excitation waveform and the second electrical excitation waveform that drives the motor.
