Power Electronics

Power electronics is about moving energy between forms — AC to DC, one DC level to another, DC back to AC — efficiently enough that the switches, magnetics, and control loops actually survive the heat and stress of real loads. You'll analyze converter topologies like buck, boost, and flyback by hand, then simulate them in LTSpice, wind your own inductors and transformers, and lay out a working board in Diptrace to characterize on the bench. It sits at the intersection of circuits, magnetics, and semiconductor physics, and underpins essentially everything that plugs into a wall or runs off a battery — motor drives, renewables, EVs, and the power supply inside every device you own.
