Hello All...
I am using triac to drive 40A R-L load...Load can vary but max load is 40A...I am bit confused how to calculate the value of snubber for triac...Plz give the detailed explaination with any helpful document if necessary..Moreover Is varistor is better or R-C snubber is better???Moreover if I used Snubberless triacs than will i need snubber then???
Awaiting 4 ur reply guys...
Thanks

 

Googling triac snubber calculation will give you lots of information, for instance this TI app note:
