Abstract

Bei einer tiefsetzenden Anpassschaltung (1) mit zwei Eingangsanschlüssen (2, 3) für eine Eingangsgleichspannung und zwei Ausgangsanschlüssen (4, 5) für eine Ausgangsgleichspannung sind zwei Kondensatoren (8, 9) zwischen die Eingangsanschlüsse (2, 3) in Reihe geschaltet. Ein DC/DC-Wandler (10), der eine galvanische Trennung (11) zwischen seiner Eingangsseite und seiner Ausgangsseite aufweist, ist eingangsseitig an den ersten (8) und ausgangsseitig an den zweiten (9) der beiden Kondensatoren angeschlossen. Die beiden Ausgangsanschlüsse (4, 5) der Anpassschaltung sind an den zweiten Kondensator (9) angeschlossen, und für den ersten Kondensator (8) ist ein aktivierbarer Bypass vorgesehen.
