A switching dc-to-dc converter employs inductance in series with the source to form an input circuit, and in series with the load to form an output circuit. Suitable switching means alternately connects an energy transfer capacitance in series in the input circuit and in the output circuit. The inductance...http://www.google.fr/patents/US4274133?utm_source=gb-gplus-shareBrevet US4274133 - DC-to-DC Converter having reduced ripple without need for adjustments
