Transcribed Image Text:
The Thyristor shown in the following figure has a latching current of 50 mA and is fired by a pulse of duration 50 us. The firing pulse is applied after 0.1 s form connecting the switch. Show that without resistor R, the thyristor will fail to remain ON when the firing pulse ends, and then find the maximum value of R to insure the firing. Neglect the Thyristor voltage drop. Plot the load voltage waveform versus supply voltage for 0.5 s time.
