Developing a 10's of MHz switching buck converter for envelope tracking, focusing on reducing parasitics in PCB layout, characterizing switching waveforms, and component selection, particullarly GaN FETs. Design and build supporting power converters with inrush and e-fuse capabilies, most notably a boost converter with an average duty cycle of 85% and efficiency greater than 95%. Most circuit validation has been conducted in Spice programs like LTspice and Pspice with some controls work… Show more Developing a 10's of MHz switching buck converter for envelope tracking, focusing on reducing parasitics in PCB layout, characterizing switching waveforms, and component selection, particullarly GaN FETs.

I managed an EECS 419, Advanced Motor Drives masters level, lab section. Focusing on hands on experimetns controlling DC motors and AC motors (Surface Mount Permanent Magnent and Imduction). Utilizing D-Space, a simulink graphical programming enviroment assisted in building code that could be flashed. As an instructor, I had a student body with multiple different backgrounds (Mechanical/Electrical/Naval Engineers) that I was able to connect with and mentor.
