It's the gospel truth Miss Coates. (Old Yeller).

EDIT: If you want to use IGBTs, I did another one that takes 24v input instead of 15v, and outputs -8v up to 15v or something like that for the igbts to help them turn off better.

Here's a picture of it:


At the bottom is an ATTiny that is pulsing the 2 inputs of the dual driver at 70khz or so. When one is 0v, the other is 5v, and vice versa. That causes the output A of the mosfet driver to go high when output B is low, and vice versa. A push-pull converter or something like that.


One of the 6 supplies. Notice D72,73,84,85 (Full wave rectifier). 6 hcpl-4506 optocouplers (u58 is one of them). 6 of ixdi604pi dual mosfet drivers (u52). One mosfet per driver output.:
