Hai..
I am using the below circuit for one of my application. For the resistive load it is working properly. But my loads are capacitive loads(SMPS) around 20W to 40W. When I try to ON the first load, Sometimes load 2 gets on for a short time. I Thought it may due to the gate noise. So I removed the 39 Ohm resistor to the gate but still the problem comes. That means even the gate is open, triac get triggered. I put some snubber circuit and all but no use. Please help me.....
