摘要:
Systems and methods are provided for controlling a double-ended inverter system having a first inverter and a second inverter. The method comprises determining a required output current and determining a desired second inverter current. The method further comprises determining a second inverter switching function, wherein only a selected leg in the second inverter is modulated at a duty cycle, determining a first inverter switching function based on the second inverter switching function, and modulating the first inverter and the second inverter using the first inverter switching function and the second inverter switching function.
