I made a PCB for ON/OFF/DIM control with MCU, Opto for ZC and one more opto to fire TRIAC and others requisite passive components to control on/off /dim the 230v appliances.
All are working correctly when the load is Lamp(CFL/Incandescent) and Fan (if component is placed either in PCB/Breadbord)
but for the case of:
1) FTL(with Magnetic choke/40W):- when the Triac is turned-ON to turn the connected FTL ON, the others output connected to others triac getting flickering(when turned OFF) with the flickering of FTL. (tested on Breadboard)
2) LED Tube Light(18W): when the Triac is turned-ON to turn the connected LED Tube Light ON, the LED getting ON correctly, but sometimes in the midst after rightly turning on it is noticed that the light of the LED Tube Light getting trembling/vibrating and a hissing noise is also noticed. (tested on PCB)
Can anyone help me out against both the case.
