A forced commutated thyristorized step-down chopper is shown in the figure. Neglect the ON-state drop across the power devices. Assume that the capacitor is initially charged to 50 V with the polarity shown in the figure. The load current (IL) can be assumed to be constant at 10 A. Initially, Th is ON and ThA is OFF. The turn-off time available to The in microseconds, when ThA is triggered, is _______. (rounded off to the nearest integer)
Correct : 10
