Abstract

Das Schutzrecht betrifft eine Brückenschaltung (10) zur Bereitstellung eines Wechselstroms an einem Phasenanschluss (AC) mit einem ersten Gleichspannungsanschluss (DC+), und einem zweiten Gleichspannungsanschluss (DC-) zum Anschluss einer Gleichstromquelle oder Gleichstromlast, einem Zwischenkreis (17), sowie eine Brücke (11) mit Brückenschaltern, die dazu eingerichtet ist, an den Gleichspannungsanschlüssen (DC+, DC-) anliegende Potentiale an einem ersten Brückenausgang (18a) und einem zweiten Brückenausgang (18b) unabhängig voneinander getaktet bereitzustellen. Ein erster Verbindungspfad (15a) und ein zweiter Verbindungspfad erstrecken sich zwischen den jeweiligen Brückenausgängen (18a) und dem Phasenanschluss (AC), wobei jeder der Verbindungspfade (18a, 18b) brückenausgangsseitig eine Filterdrossel (12a, 12b) aufweist und die Filterdrosseln (12a, 12b) der Verbindungspfade (15a, 15b) miteinander magnetisch gekoppelt sind. Ein Trennrelais (13) mit einer Mehrzahl von Relaiskontakten (14) ist derart zwischen den Brückenausgängen (18a, 18b) und dem Phasenanschluss (AC) angeordnet, dass in einem getrennten Abschnitt der Verbindungspfade (15a, 15b) jeweils mindestens einer der Relaiskontakte (14) in jedem der Verbindungspfade (15a, 15b) angeordnet ist. Weiterhin ist eine Energiewandlungsanlage mit einer solchen Brückenschaltung (10) beschrieben.
