I've seen in several places this snubber circuit composed of 2.4K and C1 in this particular case.
My question is - what's the purpose of this network exactly and how are the values for the resistor and capacitor calculated?
Does it provide a phase shift so that power triac could be turned on on zero crossing and if so, how does it work?
It's said, that it is designed for power triacs with sensitive gate Igt < 50mA. What do I do if my power triac's gate is not sensitive (> 50mA)?
