摘要： A compensation device (20) for compensating for a discharge current has a compensation current generation device (28), a potential generation device (150), active conductor terminals (61, 62, 63, 64) and a PE conductor terminal (65), which active conductor terminals (61, 62, 63, 64) have a first active conductor terminal (61) and a second active conductor terminal (62; 64), which potential generation device (150) is interconnected with the first active conductor terminal (61) and has a potential generation device terminal (155), which potential generation device (150) is designed to provide a potential at the potential generation device terminal (155) which at least temporarily differs from the potential at the first active conductor terminal (61), and which compensation current generation device (28) is designed to effect a compensation current (I_COMP) between the potential generation device terminal (155) and the PE conductor terminal (65).

摘要： 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).

摘要： 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.
