ABSTRACT:
A circuit arrangement comprising at least two high-voltage power switches (e.g. transistors) connected in series to a high voltage source. In order to ensure that the switches are automatically cut off substantially simultaneously, the control means of each switch comprise a delay element for delaying the cut-off signal. A comparison stage controls the delay caused by at least one delay element as a function of the difference between the voltage present at the junction point of the switches and a reference voltage.
