Solid State Tesla Coil
Here is a side view of the H-bridge, the four diodes are MUR3060PT 30A 600v Ultra fast diodes.
Here is another view of the H-bridge. The MOSFETs are FDH44N50 from Fairchild. They are 44A 500v MOSFETs so they should work pretty well. The heatsink is something I picked up at the local surplus shop. The board took me about an hour to make, it is just plain two sided copper drawn with a Sharpie and etched in FeCl.
