    20 million reasons to use GaN

    It was a cold and snowy day in Toronto. We were brainstorming in the basement of the local university’s advanced power electronics research lab. Ironically, the conversation was focused on heat – not actually generating it for warmth, but how to reduce it in our power converters. We had pushed MOSFETs and IGBTs to their respective limits...
