Abstract:
A method for balancing a voltage of an inverter determines an expected voltage of a capacitor based on a voltage of the capacitor at a start of a switching cycle and determines a duty cycle minimizing a value of an objective function representing a difference between the expected voltage of the capacitor and a desired voltage of the capacitor. A switching sequence controlling the inverter is selected based on the duty cycle.
