Abstract
A method and apparatus for controlling the output voltage of a boost converter including a number n of bridge devices connected in series, each bridge device including plural switches and a capacitor. The method and apparatus provide control of the switches according to a selected periodical matrix pattern including a number N of time intervals, N being a positive integer greater than 2, and in that in each time interval, the voltage between the input and the output of each ith bridge device with i from one to n, is equal to one of a null value, a number ki times a positive value, and minus the number ki times the positive value, the positive value being the result of the division of the output voltage of the boost converter including the n bridge devices by the number of time intervals N of the periodical matrix pattern.
