| Sept. 18 | Chapter 5.1-5.3.1, 5.3.4.3, and 5.3.4.4, 5.5,
5.6-5.6.1 and 5.7-5.9 class exercise:3 phase rectifier. | Three phase portion of this task | Sept. 14 |
| Sept. 20 | Chapter 7.1-7.3 | Sept. 14 | |
| Sept. 25 | Instructions for lab on DC->DC Buck converters and the TL494 Data Sheet for converter control. |
1. Mohan 3.2, 2. For the waveforms (b) and (g) in figure P3-3 calculate the average value, the RMS value and the RMS value of the fundamental frequency. 3. Using A=10 and u=20 degrees find the distortion and %THD of figure P3-3b. 4. Mohan 3.7 including a sketch of your circuit. | Sept. 14 |
| Sept. 27 | Continuation of Buck Converter lab | Oct. 19 | |
| Oct. 2 | 7.4-7.5 (Boost, Buck-boost) | Oct. 19 | |
| Oct. 4 | 7.6 (Cuk converters) | Oct. 19 | |
| Oct. 9 | review | Oct. 19 | |
| Oct. 11 | Exam 1 | Oct. 19 | |
| Oct. 16 | Fall Break | ||
| Oct. 18 | Cuk converter lab Instructions | Oct. 19 | |
| Oct. 23 | Mohan Chapter 7.7-7.8, Chapter 8.1-8.2 | Oct. 19 | |
| Oct. 25 | 5.6, 5.23 (neither of these shouldn't be an involved problem, you
might make a spice simulation to help you think it through), 5.18-use LTspice, 7.1, 7.2, 7.6-use LTspice
Note, for 5.18, and possibly 7.6, you must use a snubbing circuit in parallel with the diode as we did in class, to have your simulations finish in a reasonable time . I recommend R=100Ohm and C=100uF. | Oct. 19 | |
