摘要： A method compensates for leakage currents in a protective conductor of an electrical power converter. The method includes: using a first differential current sensor for determining a differential current depending on a phase conductor current in a phase conductor and a neutral conductor current in a neutral conductor; feeding a compensation current into the phase conductor and/or into the neutral conductor via a first compensation circuit; using a second differential current sensor for capturing a signal representing remaining residual leakage current; converting the signal representing the residual leakage current to a frequency domain; generating a compensation signal for the residual leakage current in a frequency-selective manner; converting the compensation signal to a time domain; supplying the converted compensation signal converted to the first compensation circuit or a second compensation circuit; and feeding a residual compensation current corresponding to the compensation signal into the phase conductor(s) and/or into the neutral conductor.

摘要： A rectifier arrangement for rectifying an AC voltage into a DC voltage has connections, circuit arrangements, an interconnection apparatus and an intermediate circuit. Each circuit arrangement has first and second circuit arrangement connections, between which a changeover arrangement and a coil are connected in series with the changeover arrangement. The changeover arrangements are interconnected to the intermediate circuit. The interconnection apparatus is designed to enable at least a first configuration and a second configuration. In the first configuration, the circuit arrangements form a first group and a second group, with two connections connected to the circuit arrangements in the first group, but not to the circuit arrangements in the second group, and two connections are connected to the circuit arrangements in the second group, but not to the circuit arrangements in the first group. In the second configuration, at least one of the connections is connected to all circuit arrangements.

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.
