Use of a negative gate drive can lead to a larger voltage drop during deadtime and severe losses. Andrea Gorgerino, EPC GaN devices have gone from initial R&D to mainstream designs over the last 15 years. Unfortunately, there are many misunderstandings left-over from those early-stage developments or dead-end technology branches. One of the most pernicious […]
