ABSTRACT:
A method of providing a unified power control of a motor including providing a first inverter system, a second inverter system, and a motor coupled therebetween; coupling the first inverter system coupled to a first energy source; coupling the second inverter system coupled to a secondary energy source; generating a first pulse width modulated signal; and generating a second pulse width modulated signal. The first inverter system and the second inverter system are driven with the first pulse width modulated signal and the second pulse width modulated signal respectively in order to control a fundamental component of an output voltage of the first inverter system and the second inverter system to control the motor.
