Hi,
Are measured parameters correct?
Are you talking about "measured" or "simulated" currents?
A simulation result is only as good as the informations you input in the simulation tool.
Thus I already recommended to use realistic values and a realistic circuit.
--> you used an "unrealistic" ideal switch not taking care about voltage_drop and not taking care about switch_off_conditions.
Thus I've already talked about "useless" simulation.
And there are other unrealistic things in your system: ideal capacitor, maybe the power supply, gate current limitation....
I almost never use simulations. I mostly rely on the datasheet specifications and on the application informations.
This doesn't mean that simulations are useless. You can play around with varying part values without the risk of explosion and fire. And it gives a "visual" idea about voltage and current waveforms.
Especiall the switch OFF behavior of an SCR makes that the waveform stops when the current becomes zero.
But with a Mosfet you may expect the current going negative .... causing ringing.
