The present invention concerns a method for controlling the switches of a boost converter composed of plural bridge devices connected in series, each bridge device being composed of a capacitor and plural switches. The method comprises the steps of:
-controlling the switches of each bridge device of at least a part of the plural bridge devices according to a given periodical pattern during a first time period,
- controlling, during a second time period following the first time period, the switches of each bridge device of said at least part of the plural bridge devices according to a periodical pattern previously used for controlling the switches of another bridge device of said at least part of the plural bridge devices during the first time period.
