Zusammenfassung:	An audio electronic system includes a DC switching converter comprising first and second Zeta converters, each comprising an input stage, an output stage, a first switching stage, and a second switching stage. The input stage of each Zeta converter comprises a respective input inductor having a first terminal electrically coupled to the respective first switching stage. The input inductors of the input stages of the first and second Zeta converters are magnetically coupled in such a way that when current enters the terminal of the input inductor of the first Zeta converter that is coupled to the first switch stage of the first Zeta converter, a voltage induced by the coupled current is positive at the terminal of the input inductor of the second Zeta converter that is coupled to the first switching stage of the second Zeta converter.
