Your controller circuit will need to detect the zero-crossing point and trigger the triac after the required delay. The V rating is absolute maximum V DC. Should I just connect drain and source to the AC wire?
Nice answer, but But still unclear. Because I wana create one Why not buy a dimmer switch? You are taking on an ambitious project given your current knowledge. Look up mains zero-cross detection circuits. Tahmid 1 7. Sign up using Facebook. If you want to switch VAC then use a relay. Post as a guest Name. With this scheme, you cannot control an inductive load unless you come up with some way to deal with the inductive kickback.
You use a solid-state relay using a triac internally. For your dimming application you need non zero-cross so that you can switch on at any point in the cycle. Keep these very separate from your low-voltage circuits. TOP Related Articles.
