  • Determination of phase offsets in a supply system having multiple switching converters
    Patent number: 9954428
    Abstract: A controller, and related method, to control switching elements of a plurality of voltage converters of a power system. The controller receives a signal representing an operating condition that indicates a contribution of each of the plurality of voltage converters to a ripple component of an input current or an input voltage of the power system. The controller ranks the plurality of voltage converters based on the contribution of each of the plurality of voltage converters to the ripple component. The controller calculates a switching phase offset for each switching element of the plurality of voltage converters by determining a switching order for each switching element of the plurality of voltage converters based on an alternating extremum contribution to the ripple component, and arranging control signals for each switching element of the plurality of voltage converters based on the switching order.
