Verfahren zum Bereitstellen von Strom für Verbraucher in einem Busgerät sowie Vorschalteinrichtung

摘要

The method involves limiting the maximum current intensity of a bus current (I-BUS) to a value by a current source (40). The value is dependent on the current intensity of a current source stream (I-SP), load current intensity, a load voltage (U-VSP), a temperature (T) and a time derivative. The temperature is measured in bus device. Independent claims are included for the following: (1) a switching device for bus device; and (2) a bus system with a system.
