VOLTAGE STABILIZATION APPARATUS

摘要

A voltage stabilization apparatus (1) for a motor vehicle electrical system to stabilize at least one voltage-sensitive consumer (9) is proposed. The voltage stabilization apparatus is distinguished by a DC/DC converter circuit (3), an energy storage device (5) and a changeover switch (7), which are designed and arranged so that the energy storage device (5) is changeable by the DC/DC converter circuit (3) and the changeover switch (7) enables an electrical connection between the voltage-sensitive consumer (9) and the energy storage device (5) in such a way that the energy storage device (5) in case of need supplies a stabilization voltage (USTAB) at the consumer (9).
