Abstract
A DC-to-DC switch-mode power converter. The converter includes a transformer having first and second series-connected primary windings, a first capacitor connected in series to the second primary winding, a first switch for cyclically coupling an input voltage to the first primary winding, a second capacitor, and a second switch for cyclically coupling the first and second primary windings to the second capacitor. The converter may also include a control circuit for alternately driving the first and second switches such that the first and second switches are not simultaneously conductive. The transformer includes at least one secondary winding having a secondary circuit coupled thereto. The secondary circuit may include a rectification circuit employing self-driven synchronous MOSFETs.
