According to various embodiments, a DC/DC conversion system is disclosed. The DC/DC conversion system includes a boost converter coupled to a plurality of parallel buck converters. The boost converter and plurality of buck converters each include an inductor, where the inductors are magnetically coupled to each other. The DC/DC conversion system further includes a control system configured to control the boost converter and plurality of buck converters such that combined duty cycles of the plurality of buck converters are about equal to a duty cycle of the boost converter and the duty cycles of the plurality of buck converters are modulated out of phase.
