It is my pleasure to have helped some one. The triac itself is a solid state form of an Electromagnetic relay. Thus no relays are again required. naturally you can switch faster than a relay with a triac. Anyways i'll wait for your schematic. Cheershozefa said:Does TRIAC need any delay while switching it ON/OFF?- How fast I can do switching? Thanks Once again.
i think ,R6=100E , R3=3.3K & no req. R4=5Khozefa said:Hi,
Here is the schematic, have a look.
Please tell if any extra precaution is required in the circuit.
I think it shud work fine. Only the snubber resisitor may be changed to 100E as "Sahu" mentioned. If you use BTA6/600 or BTA12/600 sieres triacs, these come with built in snubbers. Thus external circuits may be left off. Cheershozefa said:Hi, Here is the schematic, have a look.

hozefa said:Hello, I need some guidance for designing AC switch using MOSFET. This will be controlled from Microcontroller (Switching Application).
For example I have 20 bulb as a AC load and at a time only one bulb should be ON, after some time AC voltage (230V AC) will be switched to the next Bulb and it goes on (like dancing light), and switching will be controlled by Microcontroller.
So the I/P will be 230v AC and out put also 230v AC, up to 5-7Amp.
Please give some suggestion on how to design this application using MOSFET and what all criteria has to keep in mind while designing this application.
How come suddenly you are enlightened after all these questions and answers?hozefa said:Hello, I have used TRIAC for AC switch but the requirement is of High Frequency AC Switching, which can be achieved by using MOSFET. So can anyone help me in designing AC switch using MOSFET?
