Abstract

Owing to a semi-conductor switching element (with a switching path and a control electrode) having a break- down voltage, circuit arrangements comprising a plurality of such elements connected in series having to be used for application to high-voltage circuits. Power losses can become substantial, especially when the switching frequency of the circuit arrangement is increased. Improved operation can be achieved by connecting between one end of the path and the control electrode of each switching element a voltage limiting element and an electronic switch connected in series, whereby to limit the value to which the voltage will rise across each switching path on switching off the switching elements. Each electronic switch closes simultaneously with interruption or reversal of the control electrode signal, and all the switches open after the limiting values of all the voltage limiting elements have been reached. <IMAGE>
