GATE Electrical 2013 | Question: 55
The Voltage Source Inverter $(VSI)$ shown in the figure below is switched to provide a $50 Hz$, square-wave ac output voltage $(vo)$ cross an $R-L$ load. Reference polarity of $vo$ and reference direction of the output current $i_0$ are ... the $IGBTs$ during turn-on/turn-off is ZVS during turn-off ZVS during turn-on ZCS during turn-off ZCS during turn-on

GATE Electrical 2015 Set 2 | Question: 18
A series $RL$ circuit is excited at $t = 0$ by closing a switch as shown in the figure. Assuming zero initial conditions, the value of $\dfrac{d^{2}i}{dt^{2}}$ at $t=0^{+}$ is $\dfrac{V}{L} \\$ $\dfrac{-V}{R} \\$ $0 \\$ $\dfrac{-RV}{L^{2}}$
