With the growth in wide bandgap (WBG) semiconductor power devices, there is a growing need to understand the unique challenges tied to essential validation test capabilities. Double Pulse Testing is the standard method for measuring the switching parameters of WBG devices. Historically this has been a time-consuming process to set up the double pulse test. Engineers typically have to write their automation software since the instruments do not necessarily have a built-in way to configure and set up the test. Additionally, as WBG devices exceed 1000 volts and 10’s if not 100’s of amps when performing I-V Characterization, safety becomes more critical to protect the engineer or technician running the test. Proper safety protective gear is more important today as the world develops new high-power technologies to electrify the world. It requires that we understand how to properly enclose devices under test, properly use safety fixtures with automatic safety interlocks, correct cabling, and connectors, and wear the proper safety protective gear. This session, presented by Tektronix, will show various tips on making double pulse tests, including how to automate them. We will also cover proper safety precautions when working with high voltage, high current WBG devices and high-power instruments.
