Abstract

A system including at least one first converter and a filtering unit coupled to the at least one first converter is presented. The filtering unit includes at least one second converter and a plurality of inductors coupled to the at least one second converter. The system further includes a controlling unit operatively coupled to the at least one first converter and the at least one second converter. The controlling unit switches the at least one first converter to generate a first output voltage and the at least one second converter to generate a second output voltage, where the first output voltage and the second output voltage have a substantially same switching pattern.
