Abstract
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.
