I'm kinda green to this and looking for a general direction to move in.
Ford GT350 Shocks
12v 2 amp power supply
Due is running 20khz on channels 6,7,8,9
the Mosfets are getting car VDC @13-14.7V
The shocks have 1.5 ohms of resistance at rest. with a Max of 1.1 Amps
So here is the issue i have.
i need to be able to control current to the magnetic field. I find using the mosfets@20k i have a huge dead zone where the shock doesn't react till about 75% duty cycle.
I cant seem to get an accurate voltage reading or they don't make sense.
for example I'll read the voltage at 12v and Ill divide that by 1.5 ohms and get 8 amps... which the power supply cant even do.
Speed and accuracy are important.
what hardware should i be using?
