How can I simulate a transfer switch between two sources ?

I am trying to simulate a model where one source is from PV (from the inverter,3phase ac) and another is a AC source (or the grid) I tried using the two way switch under expanded phase ports but am not able to connect them.

i tried PS simulink converter.

Hello Sharat,

If you are using expaned 3 phase ports, you are using simscape blocks. If that is the case, this ideal switch can be used to connect different systems together. (use 3 of these to create a 3 phase switch if you need to, or use a 3 phase breaker in the simscape electrical library)

Please make sure to use all simscape blocks (the blue ones) for this model to make sure they can all connect. You can use the simulink-PS converter to control the switch with a simulink signal.
