Abstract

Die Erfindung betrifft einen Gleichspannungswandler (1), mit einem Transformator (2) mit einer primärseitigen Wicklung (2a) und einer sekundärseitigen Wicklung (2b, 2c) mit Mittelabgriff, einer Ausgangsinduktivität (3), welche mit dem Mittelabgriff und einem ersten Ausgangsanschluss (9a) verbunden ist, einer Synchrongleichrichterschaltung (4) mit zwei Synchrongleichrichterschaltern (14a, 14b), welche jeweils mit den endseitigen Abgriffen der sekundärseitigen Wicklung (2b, 2c) verbunden sind, und welche zum Erzeugen einer gleichgerichteten Ausgangsspannung an einem zweiten Ausgangsanschluss (9b) ausgelegt sind, und einer über die Synchrongleichrichterschaltung (4) geschalteten Snubberschaltung (5). Die Snubberschaltung weist dabei zwei Dioden (16a, 16b), welche jeweils mit den endseitigen Abgriffen der sekundärseitigen Wicklung (2b, 2c) gekoppelt sind, einen Kondensator (6), welcher mit den zwei Dioden (16a, 16b) gekoppelt ist, und welcher dazu ausgelegt ist, in der Synchrongleichrichterschaltung (4) auftretende resonante Schwingungsenergie zu speichern, und eine Entladeschaltung (7) aus einer Reihenschaltung eines Entladeschalters (18) und eines Widerstands (17) auf, wobei die Entladeschaltung (7) zwischen dem ersten Ausgangsanschluss (9a) und dem Kondensator (6) gekoppelt ist und dazu ausgelegt ist, gespeicherte Ladung in dem Kondensator (6) selektiv in den ersten Ausgangsanschluss (9a) zurückzuspeisen.
