Abstract
An isolated boost power converter comprises a magnetically permeable multi-legged core () comprising first and second outer legs () and a center leg () having an air gap () arranged therein. A boost inductor (Lboost) is wound around the center leg () or the first and second outer legs () of the magnetically permeable multi-legged core (). The boost inductor (Lboost) is electrically coupled between an input terminal () of the boost converter and a transistor driver () to be alternatingly charged and discharged with magnetic energy. A first and second series connected secondary transformer windings (SW; SW) with a center-tap () arranged in-between are wound around the first and second outer legs (), respectively, of the magnetically permeable multi-legged core (). In a first discharge state, the magnetic energy stored in the boost inductor (Lboost) is discharged by directing a discharge current from the boost inductor through a primary transformer winding (PW; PW) and in a second discharge state, the magnetic energy stored in the boost inductor (Lboost) is discharged by discharging a magnetic flux through the first and second secondary transformer windings (SW; SW).
