For 240V mains, you get 320 to 360V when rectified. The IRFP460 works well off this.

The HGTG30N60xxx IGBTs are 600V rated so they would be fine too.

Where abouts are you? If your in Australia, I would suggest Element 14, postage is free and arrives in a day or two.

wait. you have no need for doubling, and your mains voltage is what us in the USA would get using a doubler. so just inverse the operation. use a full wave bridge rectifier to charge two series capacitors. then the voltage across each cap is half of the total voltage. if you use a half bridge, you can use the tap between the caps for the "0" voltage. then use the top and bottom rails as your + and - rails. or plan accordingly if using a full bridge.
Interesting. I think this might be applied to the EVR microBrute I'm actually building. I'm gonna ask Dan.
