Abstract: A converter includes first and second input terminals and first and second output terminals. The converter also includes an output capacitor coupled between the first output terminal and the second output terminal, and a magnetic component having two input terminals and three output terminals. A first output terminal of the magnetic component is coupled through a first electronic switch to the second output terminal of the converter, a second output terminal of the magnetic component is coupled to the first output terminal of the converter, and a third output terminal of the magnetic component is coupled through a second electronic switch to the second output terminal of the electronic converter. In addition, the converter includes a switching stage configured to transfer current pulses from the first input terminal and the second input terminal of the converter to the two input terminals of the magnetic component.
