High-Frequency Power Magnetics with Multi-Material Cores

Operation in the HF regime (3-30MHz) has shown promise in achieving miniaturization of power electronics by reducing core loss. Winding loss however becomes a large limiting factor in reducing the size of power magnetic components at HF. The proposed approach to minimizing winding loss is to use multi-material cores to manipulate the magnetic flux such that winding resistance is reduced. Through investigation of different multi-material core geometries via simulation and then development of optimization methods for each geometry reduced winding loss may be achieved in these power magnetic components allowing for successful high-frequency operation and thus miniaturization.

I really enjoyed my UROP with the Power Electronics Research Group last semester and wanted to get even more hands-on EE experience. I'm also excited to delve into some interesting magnetics by investigating properties of multi-material cores.
