EECS 314 Fall 2007 HW 09 Problem 1 Student's name ___________________________ Discussion section # __________ (Last name, first name, IN INK) © 2007 Alexander Ganago Page 2 of 2 period of the input sinusoidal voltage at 60 Hz. Part 3 (10 points) Consider the circuit shown on the third diagram, which is very similar to that on the second diagram above, but the student who built it decided to ground the transformer’s output coil in addition to grounding the load resistor. Analyze and explain how the circuit operates over one period of the input sinusoidal voltage: for simplicity, consider the two moments of time, labeled T 1 and T 2 on the sketch below. For each moment of time T 1 and T 2 , do the following: 7. Explain which diodes (A, B, C, E) are conducting 8. Explain whether the current flows through the load resistor 9. Calculate the the output voltage V OUT across the load resistor Write your conclusion on the operation of the rectifier circuit with two ground nodes shown here: 10. Explain whether adding the second ground node is effective 11. Explain whether adding the second ground node is safe 12. Add any other comments on the operation of this circuit if you wish

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
