Power Electronics (PE) Notes by Arunkumar for 7th semester Electronics (EC) VTU

This is one of the major and scoring subjects of 7th semester. Similar to other Electronics subjects, this subject also consists of diagrams, equations, and numerical problems. This subject deals with the different transistor characteristics and details. So, to score in this subject you need to go through the good study materials, Books, Video lectures and etc. Especially, what I think, notes really helps students in order to understand the thing or concept better.
So to reduce your tension and pressure or if you feel the subject is tough then, here we come with the notes on the Power Electronics (PE) by Arunkumar for 7th semester Electronics and communication students. You can trust on this NOTES. But don’t make yourself depend on NOTES only. You should also follow the books at same time, as there might be some human error in the notes.
