Abstract
PURPOSE: To reduce the rated power of a voltage limiting element and control switching element by performing on-off control of main switching element such as GTO thyristor through alternative on function of two aux. thyristors.
CONSTITUTION: The capacitor C is charged through turning on of thyristor Sq then when turning the thyristor SO on, the GTO thyristor Th is turned on with high peak current by the charge of C while simultaneously the thyristor Sq is turned off by the forward voltage of diode DO. Then when turning the thyristor Sq on, the thyristor Th is turned off by the capacitor C charged with reverse polarity. Since the current of Zener diode ZD for limiting the voltage is limited by the resistors R2, R3, the rating can be reduced while since the gate current of thyristor Th is produced through the discharging of the capacitor C the size of control switching element can be reduced.
