I have four ducted fans on a platform that require 12V, 10A. I'm using a car battery as the power source for the fans, but I need a way to control the fans with a PWM wave. ive tried using a hardcore Mosfet in a simple power switch (Load on Drain, Ground on Source, PWM on Gate) but MOSFETS are so fragile, I keep blowing them, plus the heatsinks are weighing down my project. Is there a better way to do this?
More Info( The PWM is +-5V, but I can ramp it up to +-20V)
