Scope software validates wide-bandgap devices

The wide-bandgap double pulse test (WBG-DPT) application from Tektronix automates key validation measurements on wide bandgap devices such as SiC and GaN MOSFETs. Running on the company’s 4/5B/6B Series mixed-signal oscilloscopes, the WBG-DPT software provides accurate, repeatable measurements to simplify debugging and speed validation time of these WBG power semiconductors.

WBG-DPT offers an automatic WBG deskew technique and reverse recovery timing plots to make it easier for engineers to see reverse recovery details for multiple pulses overlaid on a single display. Measurements also align with JEDEC and IEC standards for double pulse testing and diode reverse recovery.

According to Tektronix, the WBG deskew technique is an industry-first that eliminates the need for rewiring and can even be performed after double pulse measurements have been taken. To simulate the effects of delays in the test setup, the software generates an alignment waveform. The engineer adjusts a few settings to match the alignment waveform with the measured waveform, as the software corrects any differences in delays. This new process reduces the deskew time from an hour or more to just 5 to 10 minutes.

The WBG-DPT application is available now for global customers.
