Abstract:
A single-stage input current shaping (S.sup.2 ICS) converter coupled to receive a line voltage, comprising:a front-end stage receiving said line voltage, including:(a) a full-bridge rectifier;(b) one or more boost inductors;(c) first and second dither sources each coupled in series with one of said boost inductors; and(d) first and second storage capacitors, coupled to said full-bridge rectifier in a voltage-doubler configuration and coupled respectively to said first and second dither sources, such that each of said first and second capacitors is charged by one of said boost inductors for storing energy for output; anda DC/DC power converter stage, coupled to both said storage capacitor and said dither source, to transfer said energy stored in said storage capacitor to an output load.
