GATE Electrical 2020 | Question: 12
Thyristor $T_{1}$ is triggered at an angle $\alpha$ (in degree), and $T_{2}$ at angle $180^{\circ}+\alpha$, in each cycle of the sinusoidal input voltage. Assume both thyristors to be ideal. To control the load power over the range $0$ to $\text{2 k W}$, the minimum ... $0^{\circ}$ to $120^{\circ}$ $60^{\circ}$ to $120^{\circ}$ $60^{\circ}$ to $180^{\circ}$

GATE Electrical 2014 Set 2 | Question: 54
A single-phase $SCR$ based $ac$ regulator is feeding power to a load consisting of $5 \Omega$ resistance and $16 \: mH$ inductance. The input supply is $230 \: V$, $50 \: Hz$ ac. The maximum firing angle at which the voltage across the device becomes zero all throughout and ... $30^\circ$ and $23 \: A$ $45^\circ$ and $23 \: A$ $45^\circ$ and $32 \: A$
