Beschreibung
Zusammenfassung:	The invention provides a power converter apparatus for converting an alternating current (AC) power input to a direct current (DC) power output. The apparatus comprises a plurality of n single-phase power converting circuits arranged in parallel, where n is equal to or greater than 2, wherein one of said n single-phase power converting circuits comprises a single-stage AC/DC converter module having an operating AC/DC converter; and each of a remaining n−1 of said single-phase power converting circuits comprises a two-stage converter module having an AC/DC converter as an input stage and a DC/DC transformer as an output stage.
