If you are still starting out with SCRs, one common simple SCR circuit is an alarm. There's lots of simple circuit diagrams that you can find just by googling it. You can even find some tutorials about it.
thanks The supply is 220v 50Hz ac.I need 60V DC output voltage .For this i need to fire the thyristor at 60 degree.The main problem is to fire the thyristor at 60 degree .please sugest me the firing circuit.
