I don't know where to get a transformer. A standard 12 v to 120 v transformer is not ideal because it is designed for sine waves and the inverter produces square waves. Even so, if you can find a 2000 watt transformer (16 amp isolation transformer, for example), you could remove the secondary and put on a 24 volt center tapped winding for a primary. The circuit you found is no good. I have designed a circuit using the SG3524 switching regulator in a non-regulated circuit. I have not built it, so no guarentees, but if it works, it will be more efficient. The circuit is at: www.geocities.com/russlk/2kwps.gif
I will be interested in comments anyone may have on this circuit.
