DIY Speed Controller for DC Loads || Control upto 100 Watts! || With under voltage protection

In this video I made a compact but powerful speed controller for DC load(specially motors) capable of handling upto 100 watts of power. The main component of the controller is the 555 timer that uses PWM and a potentiometer to vary the duty cycle at the output,thus effectively controlling the speed of a motor. The highlight of this module is the under voltage protection feature that is very useful in case we are using a battery to power the load for which the voltage should not fall beyond a certain value depending upon the battery chemistry.

Hi
Can you design single phase ac motor speed controller ?

[@UtsavShah_25]

Sure, I'll give it a try
