Abstract
A circuit for linearizing the power output of a thyristor uses a threshold switch to pulse the thyristor into the conducting mode. An accumulating capacitor provides a current to operate the threshold switch. The current that charges the accumulating capacitor arises in a DC amplifier and absolute value of sine current source. The accumulating capacitor may discharge either through the threshold switch or through a shunt switch if the threshold has not been attained within a predetermined time period. The timing device for the shunt switch is a sync pulse supply that keys off the absolute value of sine current source.
