Thank you ✅ Keysight for the offer!
Here is the Keysight test equipment used in this video!
Curve Tracer: https://www.keysight.com/jp/ja/produc...
Double Pulse Tester: https://www.keysight.com/jp/ja/produc...
For trial measurement / technical consultation, please email us 👉 [email protected]

We used the Curve Tracer and Double Pulse Tester to verify the difference in characteristics between fake and real power semiconductors.

The relationship between switching speed and gate resistance is explained in this video:    • パワー半導体の「ゲートドライブ回路」の重要性と原理について解説 #シリーズ半導体
