Their fast switching speeds, however, pose challenges in dynamic device characterization. It is further converted to 5V and -5V. Measuring of swichting losses. The initial system provides complete double-pulse test characterization and parameter extraction for Si and SiC power semiconductors with ratings up to 1.2 kV and 200 A. Analysis und characterisation of switching of power semiconductors. Moreover, using a double-pulse test, no major changes in switching characteristics were . Gallium Nitride (GaN) power devices have been in volume production since March 2010 with remarkable field reliability. loss measurement, the loss is measured at the turn -on of the first pulse which the V/I loss is zero. The GS66516T double pulse test (DPT) board is shown on the right. As shown in Figure 6, ΔRDS (ON) slightly increased as longer and higher VDS (OFF) stress was applied, confirming that our double pulse test system can evaluate the current collapse of GaN power transistors effectively. PCB layout optimization is also investigated for improved switching transients. This paper selects a 650 V enhancement GaN HEMT GS66516T from GaN Systems for characterization. It's called double pulse because two pulses are sent to the device under test (DUT) in a clamped inductive load circuit (Figure 1).

The data on the left is at 25oC and the data on the right is at . . Evaluation of 600 V direct-drive GaN HEMT and a comparison to GaN GIT ... 3(b) shows. Figure 2 The measurement setup includes the IsoVu system (left) and a DPT board with MMCX connectors (right). PDF GaN Power Semiconductor Device Dynamic Characterization GaN Systems -Confidential -2 PURPOSE The Double Pulse Test (DPT) is used to characterize theturn-on and turn-off characteristics of switching power transistors.
