Common misconceptions about the MOSFET body diode
Engineers who design power circuits around wide-bandgap semiconductors frequently make costly mistakes that relate to the switching behavior of transistors. Julian Styles | GaN Systems We need to face an awkward and embarrassing truth about ourselves in the world of power electronics. I’d like to ask you to try to be completely open and honest […]
GaN power devices, Part 1: Principles
Power devices based on gallium nitride (GaN) are rapidly becoming a viable, higher-performance alternative to silicon MOSFETs due to their higher efficiency and other favorable attributes. In recent years, discrete power-switching and power-handling devices based on gallium nitride (GaN) material have become practical and available, and these devices are now found in many power supplies […]
