A Closer Look at the Double Pulse Test

In this video, Julius Rice, Wolfspeed Power Applications Engineer, walks you through conducting a Double Pulse Test with SpeedVal Kit. Watch Julius set up the test, capture waveforms and extract switching energy from the captured waveforms. Learn how to deskew the test setup and other tips to improve measurement accuracy.

Wonderful. Thanks for sharing this. Specially the lab part.

Really nice video Where can I get this enclosure box with interlock to shut down the hight voltage ?

I have a question, looking at switch off, in the theory part the voltage is raising before the current begins to drop and thereby the loss formula. But on the measurement the voltages raise at the same time as the current drops… so the loss formula don´t match the real world, why and are there a better formula?
