can u give any suggestion how to get transfer function of this circuit???? which i attached here... as per the above steps i not able to attach PS-simulink converter... here DC input voltage is 12v and output of buck converter is around 6v with 50% d

can u give any suggestion how to get transfer function of this circuit???? which i attached here... as per the above steps i not able to attach PS-simulink converter... here DC input voltage is 12v and output of buck converter is around 6v with 50% duty cycle.. inductor of 1mH capacitor of 220uF and R is 10 ohm and i want transfer function from output to input ?

buckConverter.mdl

You can find the transfer function implementation of buck converter in the following link:

I made a simple model where you implement it in Simulink in s-domain. Hope this helps. Open the model and the parameters are automatically loaded( File->Model Properties->Callback->PreLoadFcn )

Just run the model and see the results in scope.
