Dear All,
I have a linear robot that moves along a single axis on a rail. This is driven by PMDC motors (100W/24V) on either side of the robot. Please see this video to under the type of product I am working on.
Problem: some times when the robot is climbing up an incline and for any reason slides back if the incline is too steep, the motors are acting as a generator and they fry the H bridge, Gate drive and also the rest of the circuitry.
Following is the H Bridge and Gate drive circuit. How can I protect against this?
