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 supply.
I am using the dimmable bulb as a AC Load for dimming test of my circuit.I can able to dim my bulb.But sometimes I am getting flickering in the bulb.
So,I tried to capture the input power supply.I realized that is because of power supply.
Is there any other way to control the power supply with smoothing manner to get non-flickering effect while I am dimming the bulb. ?
