Light emitted by Xenon flash tube is transmitted to phototransistor MRD300 through optical fiber. Sensitive current is amplified to triggering a string of thyristors simultaneously. Therefore, high voltage of 6000V is set on loader R. This optical trigger flip-flop can eliminate the inductance delay of general wirings. Here, the SCR devices are required to have the same rising time, aiming to prevent conduction of those slowest components from circuit triggering.
