EE HONOR CODE
2
The Electrical Engineering Department will enforce the following Honor Code that must be read and
accepted by all students.
“I have read the Honor Code and agree with its provisions. My continued enrollment in this course
constitutes full acceptance of this code. I will NOT:






Take an exam in place of someone else, or have someone take an exam in my place
Give information or receive information from another person during an exam
Use more reference material during an exam than is allowed by the instructor
Obtain a copy of an exam prior to the time it is given
Alter an exam after it has been graded and then return it to the instructor for re-grading
Leave the exam room without returning the exam to the instructor.”
Measures Dealing with Occurrences of Cheating


Department policy mandates that the student or students involved in cheating will receive an “F”

Discussion on EE136 project Fall 2004.
Objective: Build a DC/DC switch mode power supply.
Due Dates: 12/1 – 12/8 (due when you present in class)
Results:
1.
2.
Project report;
Class demonstration of your power supply;
Approach:
1.
2.
You are required to select one power supply from following three applications. You will
work alone, design, select component and build the power supply.
a. A battery charger for one cell. Input voltage will be 5 to 5.5V. Output 2A max.
b. A White light LED supply. Input voltage 3-5.5V. Output carries 4 LEDs.
You will demonstrate that your power supply can:
a. Regulate for the specified input voltage range and output load;
b. Handle input voltage transient;
c. Handle output short circuit and open circuit.
Schedule:
1.
2.
3.
4.
10/01/03 – deadline for submitting your intended application. I intend to divide the
students into two equal groups for above two applications.;
10/23/03 – Submit preliminary report on your chosen application. Content should
include but not limit to:
a. What is the application;
b. What are the solutions?
c. How are you going build the power supply?
11/3/03 – Return of your report by instructor with comments for final report and
demonstration;
12/1/03 – Start class presentation (we may schedule a Saturday for demonstration).
Hints to obtain good score on your project:
1. Do it early. Come to discuss with your instructor with your question.
2. Debug your circuit and make it work.
General hints on getting a good score from EE136:
1. come to lectures;
2. do your homework and other assignment on time (any copying or late submission will be
discounted);
3. study for your exams;
4. do your project early.
