Hi all,
I am currently working on the speed control of a DC motor by PWM using a microcontroller. The speed control is achieved by means of 8 mosfets connected in parallel. While the motor was run and tested, the ground of microcontroller PCB burnt. Am using common ground for all the PCBs. I need to know what the problem is? Is it because of the common ground? Why is the current taking the path through the Microcontroller board rather than through the Mosfets.
Kindly help me in this regard
