Patent ID: 7199535

Claim:
A double-ended inverter system for a vehicle, said double-ended inverter system comprising: a load comprising a first AC motor having a set of windings, wherein each winding of said set includes a first end and a second end; a first energy source; a first inverter system coupled to said first energy source and adapted to drive said load, wherein said first ends of said windings are coupled to said first inverter; a secondary energy source; a second inverter system coupled to said secondary energy source and adapted to drive said load, wherein said second ends of said windings are coupled to said second inverter; and a controller having an output coupled to said first inverter system and said second inverter system for providing at least one pulse width modulated signal to said first inverter system and said second inverter system to independently control a fundamental component of an output voltage of each of said first inverter system and said second inverter system to achieve a desired varying power split between said first energy source and said second energy source.
