Inhalt:
In this paper we present the results of Unclamped Inductive Switching (UIS) measurements of power GaN HEMTs comprised of p-GaN gates. Typical test waveforms and basic description of effects during discharging period of inductor are presented and discussed. It is experimentally confirmed that p-GaN HEMT devices exhibit intrinsic UIS capability. Influence of different inductances as well as different supply voltage is also analyzed.
