WebbWhat is the reason of connecting a pulse transformer at the output of thyristor triggering circuit? It is used to isolate gate triggering circuit from high power main circuit. If there any disturbance (fluctuation due to load changing ) in main circuit, gate triggering pulse should not get affected. WebbA gate triggering circuit for an SCR provides a train of pulses with a frequency of 100 Hz and a pulse width of 2 ms. If the pulse has a peak power on W, find the average power dissipated by the gate? Solution: Pulse period T = 1 / f = 1 / 100 = 10 ms Duty cycle d = TON / T = 2 / 10 = 0.2 PG (avg) = 0.2 x 2 = 0.4 W
