John Glaser received his BSEE from the University of Illinois in Urbana-Champaign and went to Motorola to design RF power amplifiers for mobile and fleet radio systems, after which he earned an MSEE and Ph.D. from the University of Arizona. He then spent two years at Hughes Missile Systems working on power electronics for TWT amplifiers, after which he joined General Electric Global Research. From 1998 to 2014, he worked on power electronics for consumer, commercial, medical, industrial, aerospace and wide-bandgap semiconductor applications, for power levels ranging from milliwatts to megawatts and frequencies ranging from 50 Hz to > 100 MHz. In 2014, he joined Efficient Power Conversion (EPC) as Director of Applications, where he develops applications, circuits, and methods to maximize the benefit of GaN power transistors, and to help engineers realize the advantages of GaN technology. He has published more than 35 papers and has been granted 33 US patents and 12 non-US patents, with several more pending, and is an IEEE Senior Member. Dr. Glaser is co-author of DC-DC Conversion Handbook, A Supplement to GaN Transistors for Efficient Power Conversion.
