Abstract
A thyristor circuit includes at least one branch including at least one thyristor, a thyristor control circuit and a current detector. The current detector is configured to detect a current value representative of an electrical current flowing through the thyristor and to input the detected current value into the thyristor control circuit. The thyristor control circuit is configured to determine a fault condition in which the detected current value exceeds a predetermined current threshold based on a deteriorated blocking ability of the thyristor. Dependent on the determination result, the thyristor control circuit triggers the thyristor into a conductive state.
