Q2. A buck regulator has an input voltage $V_s = 25$ V. The required average output voltage $V_a = 10$ V at $I_a = 0.5$ A and the peak-to-peak output ripple voltage is 10 mV. The switching frequency is 30 kHz. The peak-to-peak ripple current of the inductor is limited to 0.2 A. Determine (a) the duty cycle $k$, (b) the filter inductance $L$, (c) the filter capacitor $C$, and (d) the critical values of $L$ and $C$. (20 pts)
Suppose you read that eggs are reaping higher profits. With the theory of perfect competition in mind, what do you expect to happen over time to the following: egg prices, the profits of egg producers, the number of eggs on the market, the number of egg producers? Use graphs to support your answer. Now assume the egg industry is in long run equilibrium. Diagram long run equilibrium. Health concerns about cholesterol lead to a decrease in demand for eggs. Use a graph to demonstrate how the change affects the global egg market equilibrium. Use a second graph to show how the market change has affected the profit and level of output of an individual egg producer.
