Mini-Quizzes - 30 % (best 3 out of 4 quizzes)
Mid Sem. - 30 %
End Sem. - 40 %

Topics Covered in the Course

The course covers the fundamentals of power electronics.
Power adapter, Power semiconductor devices : Structure, operating characteristics and working of power diodes, MOSFETs, thyristors, GTOs, IGBTs, DC-DC Buck converter, DC-DC Boost Converter, Switch Realization, Flyback converter, Diode rectifier, Thyristor rectifier, Active rectifiers, Single phase Modulation, Single phase voltage source converter, Three-phase voltage source converter, DC/AC inverters, AC/DC converters.

Teaching Style

Pre-recorded lectures were already posted on youtube and a given set of lectures were supposed to be watched each week. Assignments were given almost every week and problems were discussed in interaction sessions which were conducted on MS Teams. Breakout sessions were conducted on Wednesday to clarify doubts from TAs, and interaction sessions were conducted on Friday to clarify doubts, get additional information, etc. The interaction sessions were mandatory to attend.

Tutorials/Assignments/Projects

Good difficulty. Highly recommended to attempt assignment problems before exams.

Feedback on Exams

One question was given in each quiz which was usually difficult. The midsem was of moderate difficulty. The endsem exam was very difficult.
