Optimizing discrete SiC devices
SiC FETs now include measures aimed at keeping losses down while managing fast switching waveforms. Dr. Anup Bhalla | UnitedSiC Silicon carbide (SiC) FETs have low on-resistances, fast switching speeds, and intrinsic diodes with low reverse recovery charge (QRR) and low forward-drop (VF) qualities. These qualities make SiC FETs suitable for use in active-front-end three-phase […]
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 […]
4-pin SiC MOSFETs deliver 35% lower switching loss over conventional packages
Rohm announced the availability of six new trench gate structure SiC MOSFETs (650V/1200V), the SCT3xxx xR series, ideal for server power supplies, UPS systems, solar power inverters, and EV charging stations requiring high efficiency. The SCT3xxx xR series utilizes a 4-pin package (TO-247-4L) that maximizes switching performance, making it possible to reduce switching loss by up […]
