Using Either A Buck-Boost To Design A Circuit To Control The Speed Of A Dc Motor

School of Engineering UCLan Coursework Assessment Brief Academic Year: 2021/2022 Module Title: Power Electronics Module Code: EL3813 Level 6 Assessment Title: Power Electronic Converter Design This assessment is worth 40 % of the overall module mark THE BRIEF/INSTRUCTIONS 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. PREPARATION FOR THE ASSESSMENT  Refer to power electronics lectures. Additional support will be provided during the labs. RELEASE DATES AND HAND IN DEADLINE Assessment release date is 04/01/2022. Produce a report as detailed below and submit it to Blackboard Turn-It-In by 23:59hrs on 31st March 2022. Please note that this is the final time you can submit – not the time to submit! Your feedback and mark for this assessment will be provided within the University’s 15 working day policy for feedback. SUBMISSION DETAILS Report The students should produce a report (around 2000 words) in Microsoft Word or PDF format that: 1. Describes the theory of the converter and the design process. 2. Provides a mathematical justification for the choice and sizing of each component. 3. Describe the coding (e.g. pseudo code) to control it and the feedback control system. 4. Presents the simulation results of the simulation over the working output voltage range, and for different motor loads (e.g. power outputs). 5. A final conclusion section including your recommendations for any improvements that could be made or included to the design in the future. Include the Coursework Coversheet as the first page of your report. Marking Criteria Marks breakdown is given below: 1 Description of your design process and your calculations. (40%) 2 Justification of your choice of components. (20%) 3 Present and discuss the ECAD simulation results. (20%) 4 A discussion on ways that the output could be improved. (20%) Late Work: Work submitted electronically may be submitted after the deadline to the same Turnitin assignment slot and will be automatically flagged as late. Except where an extension of the hand-in deadline date has been approved, lateness penalties will be applied in accordance with University policies. HELP AND SUPPORT  Several lab sessions are scheduled to provide you support. However, students should try to complete the assessment prior to participating at the labs. Students can obtain a PLECS license to install on their personal computers. Please contact Dr. Yapa to obtain a student license.  For support with using library resources, please contact SubjectLibrarians@uclan.ac.uk.
