A model predictive control method of a flying capacitor multi-level converter

摘要

A method of model prediction control in a flying capacitor bridge multi-level converter is disclosed. A method for predicting and controlling a model in a flying capacitor bridge multi-level converter includes the steps of: (a) determining a total terminal voltage command value; (b) determining a terminal voltage command value of each switch cell using a pair of terminal voltages of each switch cell that can be combined according to the total terminal voltage command value; And (c) determining a switching state command value of the flying capacitor bridge using an extra switching state pair that can be combined according to the terminal voltage command value of each of the switch cells.
