Q.2 You are to design a voltage regulator used to power a car radio at $V_L = 9V$ from an automobile battery whose voltage may vary between 11 V and 13.6 V. The current $I_L$ can vary between 0 (off) and 100 mA (full volume). Assume that the maximum current of the Zener diode is 10 times larger than the minimum Zener diode current. Determine the required value of the resistance $R_i$ and the power rating of the Zener diode. (15 marks) $R_i$ $I_i$ $I_L$ $V_{PS} = 11-13.6 V$ $I_Z$ $V_Z = 9 V$ Radio

The capacitor is initially charged to a voltage $V_0$ with the upper plate positive in the diode and the LC network shown in Fig. Switch S is closed at $t = 0$. Derive expressions for current through and voltage across C. Find the conduction time of the diode, peak current through the diode and final steady-state voltage across C in case $V_s = 400$ V, $V_0 = 100$ V, $L = 100$ ?H and $C = 30$ ?F. Apply PSIM/Multisim to find the voltage across the inductor and capacitor.
