custom diode in simulink?

Hello,

I would like to implement a custom semiconductor as you can do it in PSPice and similar tools. I have a custom LED i would like to use in my simulation, but I don't know how to get it's "behavior" implemented in Simulink? Is there a way?

Thanks in Advance:),

Hi Abdulkadir,

This documentation link is a good place to start for Diode modeling in Simulink: http://in.mathworks.com/help/physmod/elec/ref/diode.html

It has the following representations:

• Piecewise Linear
• Piecewise Linear Zener
• Exponential

Each of these representation has parameters that can be changed to according to your custom model. Those include sections like Reverse breakdown, Ohmic resistance, Capacitance, Temperature dependence etc.
