1. A control device for controlling a thyristor, comprising:
a triac; and
a first diode series-connected between the triac and a first terminal of the control device, wherein said first terminal is configured to be connected to a cathode gate of the thyristor; and
wherein a second terminal of the control device is configured to be connected to an anode of the thyristor;
wherein the triac has a gate connected to a third terminal of the control device that is configured to receive a control signal.
