摘要： An arrangement and method for protecting a multiple voltage supply system against voltage arc-over between the different voltage planes. For this, the voltage in the low-voltage plane of the supply system is clamped to the low-voltage value with a voltage limiter until a battery disconnect switch in the high-voltage plane of the supply system is opened and the generator output voltage in the high-voltage plane is adjusted back to the voltage value of the low-voltage plane. As a result, the high-voltage plane of the supply system is disconnected from the high-voltage sources. Consequently, the voltage in the low-voltage plane is prevented from increasing even in case of a short-circuit between both voltage planes of the supply system and the consumers in the low-voltage plane can continue to be operated safely.

摘要： A method for determining the buffering effect of the battery (2) for providing a voltage (U) for a power supply system (4), in particular for a vehicle, is provided in order to identify serviceability of a battery as easily and reliably as possible, in which method any voltage change and any current change are detected cyclically, the dynamic internal resistance of the battery is determined on the basis of the quotient of the voltage change and the current change, the specific dynamic internal resistance is monitored for exceeding an extreme value which can be predetermined, and a statement of the buffering effect of the battery is made and is output. In this case, the buffering effect of the battery is better, the smaller the quotient of the voltage change and current change.
