Anyone try a Forward Converter?
Last weekend I modified a line powered ATX supply to work off 12V. I wound a transformer, and built up the PWM control circuit. So basically half of the supply is kept intact, and the other half (AC side) is replaced. It works great to 8V, but below that it shuts down. I think I've got that problem solved, so it can go down to about 6.5V for a brief moment. (Starting the car, I measured my 2000 VW to drop the battery voltage to 7.5V. :eek: )
Anyway has anyone seen plans for such a supply? If there was enough interest I could draw up some schematics and post them here.
