Sir/Madam, I have passed my B.Tech in Electrical Engg in 2012, now I want to do M.Tech , so please tell me which branch I should choose: M.Tech in i) POWER ELECTRONICS & DRIVES OR ii) POWER ENERGY & SYSTEMS. I like Power System and its related subjects in my B.tech so a little bit attracted towards choosing POWER ENERGY & SYSTEMS, but some teacher of mine have told me to take POWER ELECTRONICS & DRIVES, so I am a bit confuse. Please explain me what are the differences between those two branches, and future aspects. Is POWER ENERGY & SYSTEMS branch is tougher or what ? Then why most faculty advice to take POWER ELECTRONICS & DRIVES ???
