Course purpose

The purpose with the course is to develop competence for the complete design process for a system of power electronics, a board power system, with advanced and complex loads in a limited product. The design process starts from the requirements/product knowledge and ends with a final assembled product, a physical product with a design that is based on the life cycle requirements of the product. This includes protective circuits/components, EMI filter, how primary and secondary converters form a board power system in a DC supplied system, how different optimizations influence the performance of the final product while still fulfilling the requirements, how different blocks works together as a highly efficient board power system and how different stage and design constraints forms the final product.

Course design

The prerequisite for this course is the course ENM061 - Power electronic converters or equivalent together with either ENM071 - Applied power electronics: Devices and implementations or DAT096 - Embedded system design project. This means that the course is continuing to build on the theory covered in these courses and it will be assumed that the students have followed the courses or have equivalent knowledge.

 

The course is designed around the practical design project where the student groups will go through the entire design process of a power electronic converter, from idea to verification measurements on the assemble design. The design process is supported by lectures for each step and each step should be documented in a written report that is submitted for assessment after each step in the process. The project is evaluated continuously both technically and according to time plan. In the end of the course the student groups should present the experiences with the other students in the course.

 

The students will perform the complete design process of a power electronic converter, from idea to verification measurements on the assemble design. The design process includes block design with different purpose and to perform thermal calculations, practical EMI (electromagnetic interference) design and transient protection design. The electric design will be a part of the course as a project task, but the complete design flow will be discussed and analysed. Process includes how to split requirement into relevant parts to be able to do correct complete design, simulation, electronic design, layout design, producibility and testability. Also, important aspects as practical fundamental understanding of how technical lifetime and MTBF have influence of design.

 

As can be seen in the teaching plan below there are:

18 lectures                          = 36 h

1 tutorials                           =   2 h

6 computer labs                 = 12 h

8 practical labs                   = 16 h

6 online help session          =   2h

1 presentation                    =   4 h

1 oral exam                         =   1h

TOTAL:                                73 h

 

This leaves 127 h for own work time, which means that you need to work on your own outside scheduled hours.

• Give introduction to the softwares during lectures in the beginning of the course
• Highlight the project specific information during the lectures.
• Added a Q&A on the lifetime calculations.
• Added more material on the controller design
• Each group will be able to book time in the CASE lab on their own, on the free sports in study week 6 to 8.

Learning objectives and syllabus

Learning objectives:

 

1. Create and evaluate different steps in a design process from idea to a finished product
2. Design a product, with focus on the power electronic parts, from a base of requirements and system knowledge, with respect to the system context and environmental conditions the board is intended to operate in.
3. Separate a complex system into fractions to simplify simulations in a practical engineering way
4. Analyse and dimension parts of a design to comply with system boundaries
5. Interpret and draw electronic schematics, including fundamental understanding and usage of electronic symbols and their connection to the physical layout of the board
6. Construct a board layout based on an electronic schematic
7. Adapt the product design to environmental condition requirements as well as applicable standards and regulations
8. Analyse and compare different types of fault and transient protections.
9. Analyse and evaluate a design from an EMI perspective, i.e. how radiated and conducted disturbances propagate and interact with different parts on the PCB and its surrounding.
10. Apply producibility and testability in the design
11. Discuss how thermal considerations impact different design choices as size/volume, humidity, indoor, outdoor, cooling, price etc.
12. Reflect over the value creation made for others
13. Plane the project, write a report to document the project and share the experiences with the other students in the course.
14. Show an ability to within the project make judgements considering sustainable developments and ethical aspects through:

• Reflection and critical judgement of relevant dimensions of sustainable development
• Handle scientific writing in an ethically defendable way, for instance related to plagiarism and authorship.
• Utilise ethical principles for data acquisition, analysis and result presentation.

Examination form

The course consists of two parts:

• Part A, Design exercise + laboratory, 4.0 credits, gradings scale Pass or Fail
• Part B, Oral examination, 3.5 credits, gradings scale Pass or Fail

 

For part A, the practical design exercise + laboratory, the students need to be presence and contribute to the project work and to each hand in of the report. The student also needs to pass the writing quiz on Canvas. For each hand in a small contribution report should be filled in. When all submissions are approved, and the experiences are shared with the other groups during the presentation session, the project work is approved, with grade Pass.

 

The individual oral examination is based on the design project, lectures and discussions during the course. The grading of the is Pass or Fail.

 

The final grade on the course is Pass or Fail. When both the practical design project and the oral examination are graded pass the final grade pass is given for the course.
