Abstract
This letter discusses the design criteria for the pulsed operation of thyristors at currents much larger than the normal surge rating. The technique has been successfully used in generating a current pulser of 40,000 A lasting 2-3 milliseconds to generate intense magnetic fields. Such abnormal operation of thyristors finds extensive applications in pulsed magnetisers, resistance welders and other high energy capacitance discharge systems.
