Hello everyone,
I have some doubts on a result i've obtained.
I'm using a circuit, as shown in the attached picture, to drive one IGBT of a module.
The wave forms shown are the voltage at the Load( Yellow ) and the current at the load ( blue).
The load is a 28Ohm Resistor.
Since the load is a resistor i was expecting the current to follow the voltage. Instead it appears to have some delay (as if there was some inductance?)
Can it be that my drive circuit is not performing as it should ? Or the problem may be with the load ?
Any ideas or sugestions on how to improve the drive circuit?
Thank you all.
