Abstract

An electric circuit is described. The electric circuit may be part of a power converter and may include a plurality of electrically connected thyristors (Ta, Tb, ..., Tn). Each thyristor (Ta, Tb, ..., Tn) has a gate terminal (26a, 26b, ..., 26n) electrically connected to a gate drive unit (28a, 28b, ..., 28n) adapted to generate gate pulses for triggering the thyristor. At least one of the plurality of gate drive units (26a, 26b, ..., 26n) is adapted to measure the gate voltage of the respective thyristor (Ta, Tb, ..., Tn) after one or more gate pulses have been applied to the respective thyristor. The measured gate voltage may be used to determine if a thyristor has not been triggered by the gate pulse(s) - e.g., if the gate voltage is below a voltage threshold.
