I designed a current limiter in a sim and it works perfectly in the real world. It gives me an output of 0-5v for 0-50 amps in one direction.
The problem however is that as soon as the direction of the controller is changed, the voltages goes much higher in the other direction. So the op amp doesn't match both ways if I've made it clear?
I've included my circuit below. I am a little stumped as to what do really do... I could always make it so that the limit output voltage are matched to the higher side, but then as soon as the direction is changed again the readings will be too low on the lower side.
So the reading from one direction of the h-bridge is 5v at 50A which is perfect, but then if the direction of the h-bridge is changed the voltage at the output of the op-amp is 5v at only 10A.
Any help is appreciated!
I've abandoned this project as it's flawed by induction issues
