EGH448 - Quiz 2 1. The diode (D) in the circuit shown in Fig. 1 has a leakage current of 50 mA at 200 V, the thyristor (TH) has the latching current of 80 mA, and the initial current of the inductor L is 0 A. For this circuit: a) Determine the minimum duration of the gate pulse for a successful turn on of the thyristor. b) Sketch the current waveform ith for two different gate pulses with the durations of 1 us and 2 us in a time window of 5 us. s (Please, use the diagrams provided at the bottom of the page).
