I hope I am understanding what your asking. If your are looking for information on how to add components to Multisim, please refer to this  website http://zone.ni.com/devzone/cda/tut/p/id/3173. There you find a detailed explaination on how to do this.

I hope this helps and Have a Nice Day

Hi Lacy,

Would you or anybody out there happen to have a simple circuit for a square to sine wave?

Ken

sariyer ,  I looked up the datasheet for your component and it says it is a PWM comtroller. If your Version of Multisim 10 has it, then there are a few generic controllers in the database. Look in your database under Power>SMPS_Transient_Virtual. This is the Power Pro version, so I have no idea if it is in other versions or not. If you have them, you can determine whether they are suitable for you purpose.

I have something for Ken. This is not an original design, but two circuits from the file you sent me that I kinda threw together. It has been tested so I know it works even though it is not perfect. I will post it below:

thanks all

Ken, I have another one for you that may be a little more simpler that the last one I posted. It still NI circuits that I have modified so I do not claim total credit for the design other than putting them together and adjusting them for this application. I hope these help in some way. The Sine Wave is still not perfect, but a real close approximation. The circuit is below:

I'm sorry, but I'm new as well to these and I'm not sure I'm in the right place to post.  This is the circuit I have and I am trying to show how it can match the math.  The problem I'm having is the picture should be depicting an ideal op amp and I'm not sure the one I chose fits the bill.

And, I'm not sure I'm getting the correct current and voltage readings on the 4Ohm resistor.  I get 200mA and 12V yet my math says different.

Can someone please help?  Thanks.
