Unformatted text preview: Δ i L b) Determine the inductance L with which Δ i L will be equal to twice the average of the inductor current. Express your answer in terms of the load resistance and the source voltage (Hint: Ignore output voltage ripple and consider charge balance of the output capacitor.) 4. (15%) Textbook Problem 4.6 5. (15%) Textbook Problem 4.15 6. (20%) Consider a threephase rectifier with inductive load, as shown below. The inductor is assumed to be large such that the load can be modeled by a constant current, I d . The threephase source voltages are balanced, with ) sin( 1 t V v a ω = . Assume now that diode D 2 has failed open (i.e., D 2 never conducts). a) Draw the waveform for the following voltages: i) Between point P and the ground ii) Between point N and the ground iii) v d b) Calculate the average output voltage, < v d >....
