PWM Speed Control Circuit Using Forward-Reverse and Regenerative Braking

Posted on Feb 5, 2014

This is a circuit design for PWM Speed DC Motor Rotation circuit. This circuit has two functions, Forward-Reverse and Regenerative Braking function. This circuit is control by MOSFET. This is the figure of the circuit; On this circuit, we can control the speed of DC 12V motor with Power MOSFET IRF150 using a signal PWM. The Relay RY1 work as contr
