Term Project
Path
Design of a Switching Converter with Feedback Loop
ƒ Each student is going to design, analyze, simulate, construct and test a
complete Switched Mode Power Supply.
ƒ Prepare term project report, must include cover page given in web page and
uploaded to ITU Ninova (otherwise zero grade).
ƒ Due date: May 14, 2013 (in class presentation)
- submit your printed report and circuit during presentation
1. Explanation of the project (1st week, assigned by the instructor),
2. Design of the converter and determining the component (switching elements,
inductor, capacitor, etc.) size and ratings (3rd week),
3. Steady-state analysis of the converter including nonidealities, i.e.,losses (4th week),
4. Simulation of the converter at steady-state operation (6th week),
5. Small-signal analysis of the converter, determination of frequency response and
obtaining key transfer functions (8th week),
6. Design of a controller for a regulated output voltage, (10th week),
7. Simulation of the converter for transient operation including the feedback loop. In
here you should show that your controller keeps the output regulated when there is
a sudden load change or input voltage variations, (11th week)
8. Construction of the converter -- power and control sections. Operating the converter
in open-loop mode (no feedback). Make necessary experimental tests starting from
minimum load to rated load, make sure that there is no noise/ground/etc problems
in power and control circuit. Compare your experimental results with theoretical
ones (12th week),
9. Close the feedback loop and determine line and load regulation (13th week),
10. Prepare the final report and presentation (14th week).

Outcomes
Switched Mode Power Supplies (SMPS) are power electronic circuits that perform
power conversion by operating a semiconductor switch in on-off mode at high
frequencies. Because of containing low loss elements (capacitor, inductor,
transformer, semiconductor switch), high efficiency, low weight and small size
make these supplies to be wide spread used in today's many applications. The aim
of this course is to give mathematical tools for steady-state and dynamic analysis.
The necessary tools required in the design of SMPS such as magnetic elements and
controllers are also the scope of this course.
1.
Steady-state analysis of switched mode power supply,
2.
Equivalent circuit modeling for a switching power supply,
3.
Design of magnetic components (i.e., inductor and transformer) in a
converter,
4.
Determination of selection criteria for component
semiconductors and controller IC in a converter
5.
Derivation of control-to-output transfer function and plotting frequency
response of converter,
6.
Feedback controller design for regulated output voltage.
