Abstract
PURPOSE: To enable blocking or stopping of the gate of a thyristor converter safely even when the gate pulse signal to a switching element becomes continuous by adding a trouble detector and a switching element thereto.
CONSTITUTION: A trouble detector 13 for dicriminating the conducting period of a switching element 7 upon detection of a voltage applied to the switching element 7 produces an abormal signal b when the switching element 7 conducts longer than normal gate pulse duration to thereby close a switching element 14 connected in parallel with a pulse transformer 6 to thus move a current flowing through the transformer 6 to the element 14 so as to protect it not to transmit the insufficient gate current to the gate of the thyristor.
