  I now have a car scale chip of gallium nitride. Now I need to model the switch and carry out simulation test in the motor drive system built by Simplorer. Please tell me how to model. I tried to use power MOSFET for feature-based modeling, but I failed. Please help, thank you.

  Hello Han,
  Please review the online help manual. Device Characterization Wizard. To start the device characterization wizard, click Twin Builder > Characterize Device > Semiconductors to open the Characterize Device dialog. You could find tutorial in the bottom of the link and I suggest you using Power MOSFET (basic dynamic). Addtionally, the gate drive should be a recommended circuit from manufacture and present real power, not simple signal. Please use a simple circuit to test if the MOSFET block works well before building a completed system circuit.
