摘要： 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.

摘要： PURPOSE:To decrease the gate power source capacity and to reduce the cost by supplying the first gate pulse to be supplied within the normal conduction period and the second gate pulse of forced ignition for evervoltage protecting purpose at the shortage time of the floating angle to the gate of SCR. CONSTITUTION:The forward and backward voltage detecting signals are converted to the electric signals through light guide 2 and via light-electric signal converter circuit 31. And floating angle shortage signal (f) is generated through floating angle decision circuit 33 to be turned to the input of pulse generator circuit 36, and output pulse (k) featuring a wide duration is delivered when the floating angle is short. On the other hand, operation signal (b) and forward voltage detection signal (c) are supplied to AND circuit 35 with output signal (e) used for the input of circuit 36. Circuit 36 produces pulse signal (j) of a narrow duration at the conduction start and intermittent time. Signal (j) and (k) are turned to signal via OR circuit 34 and then converted to the light through electric-light signal converter circuit 37 to be transmitted to the high-potential part via light guide 2. Pulse (j) featuring a narrow pulse duration is transmitted more frequently than signal (k). As a result, the gate power source capacity can be decreased as a whole, thus ensuring the cost reduction.
