I want to do a simulation for this circuit on multisim but something is wrong. Can sameone help me to do it on multisim?

 

Please attached a multisim file.

 

This is multisim file. Maybe someone can help me to get the right output.

 

First try to remove from the circuit the main transformer and bridge. And add a 20V DC voltage source the input.
And check if you get 12V at the output.

 

Hm, I think something is wrong.

 

What is wrong? But after I look at your circuit I notice that you set V1 to 230V peak and your transformer ratio is 19.3 : 1.
So this means that your input voltage is to low. AC mains voltage is 230V RMS = 326Vpeak. So please set V1 to 326V.

 

Thank you. In the output talking abuot the voltage it's ok but the current is too high.

 

What do you mean by saying that "the current is too high"?
