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.

Abstract: A circuit includes an active element, a drive circuit for the active element and a control logic for providing a control signal for the drive circuit. Further, an interface circuit is provided, which includes a primary terminal for receiving a primary signal and a secondary terminal that is galvanically isolated from the primary terminal. The interface circuit is implemented to provide the primary signal received at the primary terminal to the control logic via the secondary terminal, and to provide, based on the primary signal received at the primary terminal, by means of a rectifier circuit, an auxiliary energy signal for the drive circuit at the secondary terminal.
