ABSTRACT:
Systems and methods are provided for controlling a double-ended inverter system coupled to a first energy source and a second energy source. The method comprises determining a constant power line associated with operation of the double-ended inverter system, the constant power line representing a desired power flow to the second energy source. The method further comprises determining an operating point on the constant power line, the operating point producing a minimum power loss in the double-ended inverter system for a required output current, and modulating the double-ended inverter system using a first voltage command and a second voltage command corresponding to the operating point.
