Power Electronics


We conduct research in power electronics with applications to both magnetic brain stimulation as well as electrical energy conversion. Our current focus is on modular multilevel converters, including the modular multilevel series parallel converter (M2SPC) invented by Dr. Goetz and colleagues. In this project, we collaborate with Dr. Srdjan Lukic from NC State University.
