A thyristor is serially joined to an inductor and is shunted by a snubber circuit comprising a resistor in series with a capacitor. When subjected to a stepped change in voltage, the series combination of the inductor and the snubber circuit may become oscillatory. To prevent the voltage across the thyristor from undesirably overshooting, a tuned damping circuit is connected in parallel with the inductor, or alternatively in parallel with the snubber circuit.
