Abstract
Systems and methods for balancing phase currents of the phases of a multiphase converter include alternately connecting the phases during respective intervals to an input current and sampling, at a node of the multiphase converter that is common to the phases, the input current provided to the phases to obtain respective input current samples for the phases. While the input current samples are unequal, the intervals are adjusted to minimize inequality of the input current samples and thereby balance the phase currents.
