Hello,

What is exactly a snubber circuit?
Is it a protective circuit?
Do i require it for all the switches (IGBT/MOSFET/SCR)?
I have seen some power electronics circuits without snubbers. Iam confused.
A small electromagnetic relay is a switch. Why dont we need a snubber for that?

How can i know where to use it? And how can i calculate the component values?

Sorry for those lot of questions..

thankyou.
