Abstract

A circuit arrangement for switching a current through the emitter-collector path of a bipolar transistor whose base receives a substantially square-wave switching signal from a switching generator via a series-arranged two-terminal network having inductive reactance. This signal switches the transistor alternately to the conducting and the non-conducting state. In such a circuit arrangement, a very short fall time of the current in the emitter-collector path of the transistor is achieved in a simple and economical way in that the value of the inductive reactance decreases when a current flowing through the two-terminal network increases.
