I have read many documents on these terminologies. I find almost same working for these capacitors. Please make me clear what is the main difference between bypass capacitor, decoupling capacitor & smoothing capacitor?
Thanks

They are all capacitors with different usage. I'll give you some of my own experience.
Simply, bypass capacitor is used to bypass AC signal, since only AC voltage can go through a capacitor.
Decoupling capacitor is typically used between two electrical components, in order to bring up the signal to a certain level(in a complicate circuits, not all the devices will get the AC transition fast or accurate enough.)
smoothing capacitor is normally used in a power supply when converting AC to DC.
My answer may not be 100% right. But there are plenty of articles talking about these capacitors, you can easily look up online, google is your best friend.
