Abstract

Eine Versorgungsschaltung zur Versorgung von wenigstens zwei damit verbundenen Lasten umfasst eine getaktet betreibbare Stromquelle mit einem Steuereingang zur Stromeinstellung. Wenigstens zwei Laststränge sind parallel zwischen einen mit der Stromquelle gekoppelten Versorgungsanschluss und einen Referenzanschluss geschaltet. Jeder Laststrang weist dabei eine Last sowie einen parallel zu der Last geschalteten Ladungsspeicher auf. Ein Schalter dient zum selektiven Schalten des Strompfades des Laststranges. Ein Sensor mit einem in den Strompfad des Laststrangs geschalteten Sensorwiderstand dient zum Erfassen eines durch den geschalteten Laststrang fließenden Stroms. Weiterhin umfasst die gesteuerte Versorgungsschaltung eine Steuerschaltung, die mit dem Schalter und dem Sensor eines jeden Laststranges gekoppelt ist, zum zeitlich gemultiplexten Ansteuern eines jeden Laststranges.
