Abstract
An electrical power system for a six-phase electric motor having a first set of three-phase windings and a second set of three-phase windings. A first pulse width modulator operates at a conversion frequency and at a first phase which converts a DC power source to an alternating current to power the motor. The first pulse width modulator is electrically connected to the first set of three-phase windings. Similarly, a second pulse width modulator also operates at the same conversion frequency and at a second phase which converts the DC power to alternating current to power the second set of three-phase windings. The first and second phases of the first and second pulse width modulators are offset between 80-100 degrees.
