Abstract

Die Erfindung betrifft insbesondere ein Verfahren und eine Spannungsversorgungsvorrichtung (100) zur Stabilisierung einer Versorgungsspannung für mindestens einen elektronischen Verbraucher (A, B), insbesondere in einem Kraftfahrzeug. Bei den traditionellen Spannungsversorgungsvorrichtungen sind in der Regel voluminöse Kapazitäten erforderlich, um ein unerwünschtes Einbrechen der den Verbrauchern zugeführten Versorgungsspannung zu verhindern. Um diese Kapazitäten kleiner und damit auch platzsparender gestalten zu können, wird erfindungsgemäß vorgeschlagen, einen Teil der von den Kapazitäten verrichteten Pufferarbeit dadurch einzusparen, dass zumindest einzelne elektronische Verbraucher (A, B), die eine elektronische Reglereinrichtung (120), von der sie ihre jeweilige Versorgungsspannung (UA, UB) beziehen, belasten, in einen Energiesparmodus versetzt oder abgeschaltet werden, wenn bei der Eingangsspannung für diese Spannungsreglereinrichtung Instabilitäten insbesondere in Form von Spannungseinbrüchen festgestellt werden.

In particular, the invention relates to a method and a power supply device (100) for stabilizing a supply voltage for at least one electronic consumer (A, B), in particular in a motor vehicle. In the traditional power supply devices voluminous capacitors are usually required to prevent unwanted break-in of the supply voltage supplied to the consumers. In order to make these capacities smaller and thus space-saving, it is proposed according to the invention to save a portion of the buffer work performed by the capacities by at least individual electronic consumers (A, B) having an electronic control device (120) from which they receive their refer to respective supply voltage (U A , U B ), load, be placed in a power saving mode or switched off when the input voltage for this voltage regulator instabilities, especially in the form of voltage drops are detected.
