ECE 529: Utility Applications of Power Electronics Session 5; Page 1/2 Spring 2009 ECE 529: Homework #1 Due Session 8 (February 2 on campus, February 16 for Engineering Outreach) 1. Do the following for each of the 4 circuits below: A . Plot v o (t) versus time B . Plot the current indicated in the figure versus time C. Comment how the behavior and topology of each circuit relates to the fundamental rules of power electronics i r (t) 100 V + - 10 t = 0 + - v o (t) 100 µ F Case 1: Where v o 0 () 0V = i L (t) 100 V + - 10 t = 0 + - v o (t) 100 µ H Case 2: i c (t) 10 A 10 t = 0 + - v o (t) = v c (t) 100 µ F Case 3: Where v o 0 = i L (t) 10 A 10 t = 0 + - v o (t) = v c (t) 100 µΗ Case 4:
