dc fan

Hello all, I need to run a 12V/0.6A dc fan to cool the MOSFETs of an inverter with 1kV input. it would be overkill to use some power supply to step down the 1kV to 12V or any DCtoDC converter!.. I thought of using just a resistor divider to step down the voltage to an acceptable range to use a...

Hi guys, If anyone can help me I'm willing to make a donation for your time. Here's the schematics I'm looking for including some component specs: DC Fan (12V) speed control circuit dependent on temperature ranging from 25 to 100 degrees Celsius with smooth changes in speed all the way up to...
