I am using traic based dimmer circuit for regulating my ceiling fan. when the fan is regulated to low speed the other loads(incandescent,tube light,LED) in the room are flickering. when i increase the fan speed to certain level the flickering stops. i've tried using same circuit in my friend's home. Everything works fine(No flickering observed). I am observing this flickering at low speed let say value of 40% power
can any one please suggest me the solution . thank you.
