This circuit will works.but I am not sure that this is controllable.It will be controllable if you remove the R3 resistor and interchange the triac main terminals. ( Means replace MT1 with MT2 & replace MT2 to MT1).
In my board has both AC and DC Components.Both references connected with Diode.(Anode with Neutral and cathode with ground).
I can power the board through both AC and DC Supply. I need to measure the AC load Current.Load can get close once triac gate triggered.that load current sensed by...
LED Bulb Dimming with Triac
I had designed the dimming circuit with TRIAC.By changning conduction angle of triac using PWM signal,I can change the luminance of bulb.That means dimming.I have used the snubber circuit also to prevent the damage of the triac from the instant transcient of power...
