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 $32 \: A$

GATE Electrical 2016 Set 2 | Question: 45
A full-bridge converter supplying an $RLE$ load is shown in figure. The firing angle of the bridge converter is $120$°. The supply voltage $v_{m}(t) =200\pi \sin (100\pi t) V, R=20\Omega, E=800 V$. The inductor $L$ is large ... output current $I_{L}$ a smooth dc current. Switches are lossless. The real power fed back to the source, in $kW$, is _________.
