true, to some extent. with water heater elements you do have a wide range to choose from but they won't be an exact fit, will still need pwm on one or more of them.

Bruce,
This program is about heaters.  It is not THAT cool  8)

OH,
I was recently working on a schematic using a LT1154 FET gate driver.

Suitable for this project?
(It's a bit complicated, with current monitoring and fault protection built in... but I wouldn't know if these features are common for gate drivers or not).

4.5V to 18V Supply Range

it would work on a 12v system.

these are good for a 48v system.. theoretically. http://www.linear.com/product/LT1910 3$ each though...

OperaHouse:
I can't see a real need for a high side FET driver in this project.  It certainly does not need a high speed driver. Those will get most people in a lot of trouble due to fast rise times.  All that is needed is a handful of PC817 opto isolators to act ah a 12V driver. I should post these little modules I make that are ideal and cheap.

Aswanirahil:
Nice information shared.  :)
