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.

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.
