Using either a Buck-Boost or a Fly-back Converter, student will be required to design a circuit to control the speed of a DC Motor by supplying a voltage in the range from 30V to 60 V to the DC Motor
This assignment is designed to enhance, and allow you to demonstrate, your power
electronic design and analysis skills. Using either a Buck-Boost or a Fly-back Converter,
student will be required to design a circuit to control the speed of a DC Motor by supplying a
voltage in the range from 30V to 60 V to the DC Motor. The input to the converter is supplied
from a 50V DC power supply. The power rating of the Motor is 1.5 kW. Students will need to
design the converter, produce the mathematical calculations to justify their design, and then
choose commercially available components to meet that design. The code to activate the
switching device of the converter is to be written in pseudo code.
Students will be required to simulate their design using the PLECS electronic software
simulation package. Please contact Dr. Yapa to obtain a student license.
Task:
You need to do the following things:
1. Design a circuit to meet the above specification.
2. The students should make necessary calculations for diodes, transistors, inductors, and
capacitors.
3. Illustrate your circuit design using a schematic diagram and simulate your circuit design using PLECS.
4. Choose commercially available components for your design, and adjust your design for these none ideal values if necessary.
5. Document your results in a report, and submit your report and demonstrate your design.
