氮化镓功率半导体器件动态导通电阻的表征与建模

Gallium nitride high-electron-mobility transistors (GaN-HEMTs) suffer from trapping effects that increases device on-state resistance (RDS(on)) above its theoretical value. This increase is a function of the applied dc bias when the device is in its off state, and the time which the device is biased for. Thus, dynamic RDS(on) of different commercial GaN-HEMTs are characterised at different bias vo...
