Abstract
The present invention concerns a method for controlling an output voltage of a boost converter composed of n bridge devices connected in series, each bridge device being composed of plural switches and a capacitor, the switches being controlled by periodical patterns decomposed in time intervals. In each time interval of a first and at least one second periodical patterns, the voltage between the input and the output of each ith bridge device with i from one to n, is equal to a null value, or an integer number ktimes a first and at least on second positive value, or minus the number ktimes the first and at least one second positive value, and in each time interval of at least one third periodical pattern, the voltage between the input and the output of each ith bridge device with i from one to n, being equal to a null value, or an integer number ptimes and at least one third positive value, or minus the number ptimes the at least one third positive value, at least one number kbeing different from the number p.
