Abstract

Circuit arrangement for limiting the switching-on current and for overvoltage protection in the case of pulsed power supply apparatuses having a field-effect transistor (91) which limits the charging current of a storage capacitor (92) on the input side and ensures protection against overvoltages on the storage capacitor (92). In order effectively to limit the charging current over a wide input voltage range, a differential amplifier is controlled by the input voltage in additional to the actual value and desired value of the current. The circuit arrangement is particularly suitable for plug-in assemblies having voltage converters for supplying devices used in electrical telecommunications technology. <IMAGE>
