hi..need some help here..do any of you know how to replace the switch network of boost converter with averaged switch model and simulate it on pspice which need to create a model and the subcircuit...thanks a lot )

Switch-Mode Power Supply Spice Cookbook covers it and includes a pspice model - it is included in smpsrecipes.lib and you can see the example netlist in average_boost_Vm.net for voltage mode.

I don't use pspice so I don't know if there are symbols made - if not, it's easy to make them.

good luck!

You have to use model editor in Pspice to create capture symbols.

If your using Basso's models you can refer to his book here.

Check his web site ready made pwm controllers with capture symbols here as well as other spice SMPS stuff.

Go here and use these models.
