This video demonstrates how to test a gate drive signal for power electronics devices like induction cookers, without connecting an IGBT. The presenter explains how to use an oscilloscope to capture the signal, even when the IGBT is not present, and provides specific settings for the oscilloscope. This technique allows for troubleshooting and verifying the gate drive signal without needing to install the high-power IGBT component.
