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.

The damper preferably includes two chambers connected by a controllable bypass. One of the chambers becomes smaller during compression of the suspension system, and one becomes smaller during expansion. A controllable throttle and/or valve is provided in the bypass to adjust the damping characteristic of the absorber. The circuitry produces control signals H and w which are representative of the average height of the overall road surface undulations, and a ratio of average heights of long-wave and short-wave undulations, respectively.
