Claim Text:
1. A method for regulating cross-current flow within a power converter system comprising: measuring, by a controller comprising a proportional control, an integral control, and at least one resonator control, an existing amount of cross current within each of a plurality of converters within the power converter system; summing, by the controller, the existing amount of cross current within each of a plurality of converters to create a summed cross current; applying, by the controller, a selective current control within the plurality of converters to suppress a common mode component, a first differential mode component, and a second differential mode component within the summed crossed current; calculating, within one of the plurality of converters, the common mode component of the summed cross current formed by summing a current first current from a first phase of a converter, a second current from a second phase of the converter, and a third current from a third phase of the converter; and wherein the common mode component within each of a plurality of dominant harmonics within the one of the plurality of converters is suppressed to a value approximately near zero using the controller.
