Abstract
The present invention relates to power converters of the type known generally as switch mode power converters (SMPCs). In particular, the present invention addresses the problem of reducing thermal stress across the phases of a multi phase converter. Specifically, a method of controlling a multi-phase switch mode power arrangement is provided. The multi-phase arrangement comprises a plurality of phases configured to deliver DC power to a common load. The method comprises the steps of: determining the thermal stress of each phase along with at least one other stress for each phase and controlling the share of DC power provided by the individual phases in an effort to equalize the thermal and other stress across the individual phases.
