The light of xenon spark tube is transported to photistor MRD300 by optical fiber.The photosensitive electric current can trigger a series of thyristors after it is amplified,and offer load RL 6000V voltage.The manner of photoelectric trigger can eliminate the inductance delay generated by normal trigger's line.It requires that thyristors have the same risetime,so that can protect the circuit from triggering by those slowest inductive components.
