Review HW 6, 3:00 pm Fri, 08/30 FINAL EXAM 8 am - 10 am HOMEWORKHomeworks will be assigned every other day, there are six homeworks in total. Homework statements along with due dates are shown in the calendar above and will also be posted in Assignments/Homeworks section in eLearn and Gradescope. Keep in mind that ev代 写EE 123 POWER ELECTRONICS SYLLABUS Summer 2024R en though you need to solve all required problems in homeworks, only two randomly selected homeworks will be actually chosen for grading. Non-required problems are indicated inside the homework assignments, and won’t be graded. Use them for practice purposes. Solutions to all problems, required or not, will be posted under corresponding homework assignments in Canvas. In general, homeworks will be due at 11:59 pm on the due dates except homeworks 3 and 6 that will be due at 3 pm. This is because I will need to post solutions before the exams on the following days. Discussion of homework problems with the instructor, TA, and/or classmates will be done via Piazza. All homeworks must be completed individually and submitted for grading via Gradescope, not by email. You can use your mobile phone to scan your handwritten solutions and save them in a pdf format, for example, with CamScanner app (www.camscanner.com). A short tutorial on Gradescope usage is provided under Assignments folder in eLearn.No late homework will be accepted. LABORATORY EXPERIMENTS All labs are LTspice software based and will need to be conducted at your own location. Lab manuals can be found under Modules/Laboratories section in eLearn. Discussion of lab experiments with TA, and/or other students is encouraged. Usage of Piazza is encouraged for this purpose. Laboratories are based on LTspice software from Linear Technology, a free and very powerful Spice simulation environment,www.analog.com/en/design-c… simulator.html . Additional LTspice power electronics library specifically designed for EE123 can be found in eLearn/Canvas under Modules/Laboratories section. Laboratories will cover majority of power electronic circuits discussed in class.You are expected to read the lab descriptions, and complete the pre-lab before starting lab assignments.Lab reports are to be submitted for grading within the time-frames indicated in the lab assignments via Gradescope, not by email. Late submission will lead to a 10-point score deduction. Guidelines for the lab report must be followed.EXAMS Midterm: ONLINE, Thursday, 08/15/2024 during regular lecture hoursFinal: ONLINE, Friday, 08/30/2024, 8:00 a.m. – 10:00 a.m.All exams are open book and notes, only printed and/or handwritten materials will be allowed on the test. Electronics version of notes, textbooks, etc. will be strictly disallowed. Exams will be proctored by our TA online. Make sure that your desk and you (arms and head) are visible by our TA at all times. Laptops/PC’s can only be used for delivering video to our proctor via Zoom software. Communication gadgets, tablets, cell-phones, etc. must be off. During tests, 3 min long breaks will be allowed with proctor permission. Make-up exams are possible only under circumstances of medical emergency or sickness. WX：codehelp
