Hi MathWorks Support Team,
I am on working power electronics related project. My question is in regards with ideal MOSFET and N-Channel MOSFET. I am able to provide gating signal to ideal MOSFET from a pulse generator via Simulink to PS converter but the same gating signal, cannot be attached to the N-Channel MOSFET. I really appreciate your help.
Best Regards,
Behnam

This problem may be due to the restrictions imposed on the signal types which can be given as input to the n-channel MOSFET block. According to the MATLAB documentation for an ideal MOSFET, the gate terminal port “G” accepts either a physical signal or an electrical port. Hence it may be able to accept the physical signal generated by the “Simulink-PS Converter”. But the n-channel MOSFET accepts only electrical ports as input to the gate terminal.
A possible workaround in this case is to use a pulse generator block from the “Simscape Elctrical Library”. One suggestion may be to use the “Pulse Voltage Source” block from the “Electrical Sources” library in “Simscape” which offers similar capabilities.
You may also make use of the following documentation link on “Pulse Voltage Source” for further clarification
