2.8.1 Turn-On Measurements

The following table shows the Augmented setting for Turn-On measurements.

The following results were obtained during the testing:
  • Less cross conduction observed on the VGS signal than the waveform without the Augmented setting.
  • The current overshoot is reduced from 34.4A to 19.7A. Eon losses are increased from 149 µJ to 391 µJ.
  • With an increase in RGon value, Eon losses are more, and cross conduction is observed on VGS.
The following figures show the effect and oscilloscope waveform for with and without the Turn-On Augmented measurement settings, with the RGon value set to 0.55Ω.
