Genomsnitt: 2.81 - Didn"t live up to the name of the course, not any applications at all.» (Poor) 18. What should definitely be preserved to next year?- The project and tutorials.»- guest lectures» - I think the literature is ok» - the project work should be expanded further.» - dc-dc converters, dc-ac, ac-dc protecion of components» - The project and guest lecturer» - the project» - Computer exercise with goals within reason.» - project (with marks), guest lecture (HVDC)» - study visit» - The project. It gives a practical overview of the course and I thinck that it is an important subject. It allows apply the knowlegdes to a good real problem, with a real board. The time for lectures and tutorials is really well distributed.» - study trip» - The project, HVDC study visit, computer excercise, free handouts.» 19. What should definitely be changed to next year?- Lecturing, slide material and less time and focus on the internal behaviour of the semiconductors.»- A better structure of the course: What to learn and what areas that are the most important to now about.» - computer exercise» - 1.The course should be splitted into two courses: a.Power semiconductor device b.Power electronics applications This will be really helpful to grasp the topic 2..The project work should be changed or improved. 3.The assistant contribution must be improved... 4.The lecturer way of teaching was not that useful. 5.Computer excercises were not designed properly » - the tutorial sessions were not helpful to me. the tutor should be one who can explain more what he/she is doing.they just come and write what they have. if this is the case, then i can simply print them from the homepage, and i usually do that. » - Project, it doesnt help much to understand the things. We need more help/instruction to understand or to know what and how to deal with the work!» - More cooperation and education in teaching technology of involved personel, clearer goals of the course, practical applications of the thechnology» - The content of the course should be revised otherwise its difficult for students to learn. » - to add more time in power electronics application, especially in home appliance and industry application.» - No semicondcution part didn"t match with the rest of the course.» - Lenas tutorials. Like i said nothing personal, but that attitude combined with false calculations and wrong statements made the tutorials very dull and non educational.» - computer exercise 2 and 3» - I wouldn"t change anything» - More serious help on the project.» - Remove the semiconductor part completely!! The calculation part of it feels really of no use. This is most likely nothing that we will do. Put more focus on FACTS rather. Some of the semiconductor theory is really good to have, but the calculations with regions and such feels really unnecessary.» - Computer exercices: supervision. Tutorials: supervision... And the contain of the course (speak more about power electronic home/industry applications)» (den här kommentaren har blivit redigerad i efterhand) 20. Your comments on the study visit- Did not attend. For next year, put the study visit in the first or second week and maybe go to Ringhals instead.»- VERY BAD that Torbjörn didn"t manage to find a visit that ALL students could attent. Now the number of participants for the visit was "filled" very quick and I couldn"t come along. He would have booked two occations from the start. Now he only emailed us and told us to email him if we where intressted in a 2nd visit. In this case it"s really hard for us to know when it is and to plan our time.» - I havent participated» - Not visited yet» - It brings the theory to reality. Its good» - it"s very useful to understanding about the theory.» - Nice but have fitted better in the PSO course. » - DNA» - Nice » - good » - I did not go» - Interesting! but Vattenfall should be sending two persons to guide us.» - Great! Really intresting! Many things from it helped me get a better understanding both from a PEDA but also HV perspective.» 21. What did you think of the guest lectures?- Missed ABB. The other one about siliconcarbide didn"t give me that much. »- Bad that the time for one of them where rescheduled so that I couldn"t attend. The one I attended was good and I leared alot.» - very interesting» - The ABB lecturusefule on FACTS was good The other two lectures from Volvo and Transic were not that » - their topics are very interesting.but they must have the capability to explain it. some make it very boring. they must be entertaining.» - The one from ABB abt HDVC is quite good but the one from TranSic is rather poor!» - ok» - Its a good idea because it shows the students that what is learnt in class exists in real life.» - it"s very useful.» - Good» - Good, exactly what we need at the end of our studies.» - HVDC was good» - good connection with companies» - Interesting. It gives an idea about last trends of the course topics in the industry.» - ok» - Intresing, all of them, especially the FACTS one, but also TranSiC.» 22. Which part(s) of the course contained to few application examples ?- -»- The applications part in General» - chapter 10, the control part is one of the most important ones,yet few was done on it.» - ups, converters, » - ac-dc converters, dc -ac ups» - home application and industry application (manufacture industry) » - didn"t feel the real application connection at all. Not what the are used for.» - Maybe the guest tutorials otherwise, none.» - Almost all » - dunno» 23. Which part(s) of the course contained to many unnecessary details ?- semiconductor...»- -» - Drive ciruits » - Hard to say, think over this when planning the course and don"t forget to include it in the goals of the course» - power electronics component.» - semi conducting part» - The course itself contained alot of unnecessary details. Narrow it down and concentrate on the important things.» - Component power part of power electronic.» - the last part semiconductor » - the last part , which delt with the physics of the power semiconductors» - dunno yet» - Semiconductor part. Can skip the calculations there and focus on other things.» 24. Which part(s) of the course was/were most difficult ?- All the parts where you didn"t get enough guidance and had to sit in hours to solve a problem.»- Power semiconductor devices, because it was told in four lectures only.» - Curve forms... » - resonance component and power electronics component» - Nothing special was difficult, just to damn much to do.» - ZVS/ZCS, design, MOSFET (many things to know)» - EMI» - resonant converters» - Resonant converters.» 25. Which part(s) of the course was/were most interesting ?- snubber circuits and other areas that you might come in contact with and easily can simulate.»- -» - HVDC, FATS» - HVDC or chapter 18 in general» - snubber and gate driver circuit and power electronics application» - the short part about HVDC applications and like that...» - The guest lecture from TranSiC.» - snubber, battery applications, and the few examples (would be better to get more)» - The last part, semiconductor devices» - hvdc» - FACTS, EMI» 26. Which part(s) of the course was/were least interesting?- -»- semiconductors» - Power semiconductor devices» - semiconductor physics» - power electronics component.» - semi conduction part» - The tutorials.» - Design, ZCS/ZVS» - resonant converters» - semiconductors» 27. Additional comments- The handouts were not as helpful as they use to/should be. Toooo many and without any helping text... The lectures are a bit messy and cover far too much.. Give out more solutions to problems and the right answers to all relevant problems...!! Without at least the right answers no»- -» - i want to say something on this course. it is very interesting course where i was fond of during my undergraduate studies. but now i fill like am begining to hate it because of some part of the lectures and the tutor,she was not helpful to me. one more thing, the lectures are some times disturbing because the lecturer,sometimes he is in chapter 28 then goes back to 21. the text book is arranged in order that details go further to the end of the book. there are things we have to know in, say chapter 27 before going to chapter 29. so i recommend that lectures be given in line with textbooks.May be the project has made such disorders because it has to begin early.but i think it is not helpful in this way.» - the course is good» - The course was too deep. I won"t be a power electric designer.» - Common guys, you can do alot better.» - The explaination from the lectures and turoials are the same in the bookand on the handouts, so should we skip them and study onle at home ????? It should not be like that» - nope»
