Zusammenfassung:A method for operating a switching power converter to reduce ripple current magnitude includes (1) controlling duty cycle of a plurality power stages of the switching power converter to regulate at least one parameter of the switching power converter, each power stage including a respective power transfer winding, and (2) controlling an injection stage of the switching power converter to reduce voltage across leakage inductance of each power transfer winding, the injection stage of the switching power converter including a boost winding forming at least one turn around a respective leakage magnetic flux path of each power transfer winding.
