Abstract: A rectifier arrangement (20) for rectifying an AC voltage into a DC voltage has a first connection (21), a second connection (22), a third connection (23) and a fourth connection (24), which rectifier arrangement (20) has an intermediate circuit (50) with a first line (51), a second line (52) and a node point (53), which node point (53) is connected to the first line (51) via at least one first capacitor (61) and to the second line (52) via at least one second capacitor (62), which first connection (21), second connection (22) and third connection (23) are each connected to a star point (40) via an associated circuit arrangement (31, 32, 33), which fourth connection (24) is likewise connected to the star point (40), and which star point (40) is connected to the node point (53) via a controllable switch (45).

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).

Abstract: A method for controlling a charging apparatus of a vehicle, in particular an electric or hybrid vehicle, wherein the charging apparatus has a charging device including a protection and monitoring device. The vehicle includes a high-voltage on-board power system and an electrical energy storage apparatus connected to the high-voltage on-board power system. The method includes electrically connecting the high-voltage on-board power system to charging connections of an energy supply system by the charging apparatus. The charging connections include a neutral conductor, a protective conductor and at least one phase conductor. A protective conductor resistance is detected between the neutral conductor and the protective conductor by feeding in a test current by the protection and monitoring device. A frequency of the test current is filtered out of the compensation frequency range on a narrowband basis.
