Abstract
PURPOSE:To reduce di/dt of a GTO thyristor to make a large-capacity power source for a control circuit needless by discharging the charged electric charge of a capacitor for dV/dt control through a thyristor for ignition. CONSTITUTION:GTO thyristor 1 is equipped with capacitor 3 for dV/dt prevention, diode 4 for charging capacitor 3, and discharge current limiting resistance 5 besides diode 2 for feedback. The ignition circuit of the thyristor is formed by a series circuit, which consists of current limiting resistance 6 provided between the high voltage- side terminal of capacitor 3 and the gate of thyristor 1, DIAC 7 as a negative resistance element which performs ON operation under a prescribed voltage, thyristor 8 for ignition, and capacitor 9, and trigger circuit 10 of thyristor 8. The turning- off circuit of thyristor 1 is formed by a series circuit, which consists of DIAC 11 provided between the gate and the cathode of thyristor 1, thyristor 12 for turning-off, and reverse current stopping diode 13, and trigger circuit 14 of thyristor 12.
