A new method is proposed in this paper to investigate the influence of current collapse effect on the $I_{d}-V_{ds}$ characteristics of GaN-HEMTs in high voltage region based on a modified H-bridge circuit. The measured $I_{d}-V_{ds}$ characteristics with and without the $V_{ds}$ bias are compared, which shows the effect of charge trapping due to the $V_{ds}$ bias on device $I_{d}-V_{ds}$ characteristics in saturation region. These data will be used for a device model including the current collapse effect in full $I_{d}-V_{ds}$ region.
