Abstract

A rectifier assembly (20) for rectifying an AC voltage into a DC voltage has at least one first terminal (21, 22, 23), a second terminal (24) and an intermediate circuit (50). The first terminal (21, 22, 23) is connected via a circuit (31, 32, 33) to a neutral point (40), and the second terminal (24) is connected to the neutral point (40). The circuit arrangement (31, 32, 33) has a first branch (81) and a second branch (82) connected in parallel with the first branch (81). Both branches (81, 82) comprise a changeover arrangement (92, 93) and a coil (91, 94) connected in series with the changeover arrangement. The coil (91) in the first branch (81) is on the side of the changeover arrangement (92) averted from the neutral point (40), and the coil (94) in the second branch (82) is on the side facing the neutral point (40).
