3000 watt inverter

[fbifido]

Hi,

I have seen a dc-to-ac inverter on this site before, it was this, maybe

http://www.uoguelph.ca/~antoon/circ/555dcac.html

and i think that this diagram does not work in multisim.

Is there any multisim sample diagram for a (12vDC to 120vAC 3000 watt) inverter?

If no! can anyone build one in (multisim & ultiboard) and upload the files?

I do not believe you will get even close to 3kW out of this circuit referenced here, however I quickly put together a similar circuit based on this link and it seems to behave as a DC to AC converter with adjustable 50/60 Hz frequency.  But the concept is here as a starting point for your research...   Also note the design functionality will be very dependent on the transformer used and the anticipated loading... A good reference should be easy to find as there are a variety of good texts and web sites related to the design or selection of an appropriate transformer - and the associated SPICE modeling to use.
