Abstract

The circuit arrangement contains voltage-dependent elements, resistors, a transformer, a diode, a controllable semiconductor switching element and a Zener diode, with an output terminal which is formed by the first output electrode of the controllable semiconductor switching element, with a second output terminal which is formed by the second output electrode of the controllable semiconductor switching element, with a resistor which is connected between the first input electrode of the controllable semiconductor switching element and the second input electrode of the controllable semiconductor switching element, with a Zener diode, the anode of which is connected to the second input electrode of the controllable semiconductor switching element and the cathode of which is connected to the anode of the diode. The invention achieves the object of creating a circuit by providing between the two input terminals two parallel branches consisting in each case of a series circuit of a voltage-dependent element with a resistor in opposite sequence, by connecting to the centres of these branches the primary winding of a transformer, the secondary winding of which is connected, on the one hand, via a resistor to a first input electrode of the controllable semiconductor switching element and, on the other hand, to its second input electrode, and by connecting a Zener diode and a further resistor in parallel with these two branches.
