Abstract
A method of controlling a multilevel power converter may include measuring an input voltage at a converter input, determining a half input voltage based on the input voltage; measuring a flying capacitor voltage across the flying capacitor; determining an error voltage based on a difference between the flying capacitor voltage and the half input voltage; generating an inductor current window having an inductor peak current and a valley inductor current; modulating the inductor peak current into an upper inductor peak current and a lower inductor peak current based on the error voltage; and operating the multilevel power converter to produce an output current through an inductor to a converter output, the output current being within the inductor current window and based on a sequence of pulse width modulation states.
