V8meathead Posted December 10, 2005 Report Share Posted December 10, 2005 Used to stop switching transients right? Can anyone explain this in more detail? Thanks. Quote Link to comment Share on other sites More sharing options...
prateeksikka Posted December 11, 2005 Report Share Posted December 11, 2005 hi friend!snubber capacitors are used to protect expensive devices like thyristors against surge voltages which may appear across them in form of sudden spikes.capacitor acts as short fo high frquency and current does not flow through the device initially but increases slowly as the cap is charged....thats it Quote Link to comment Share on other sites More sharing options...
audioguru Posted December 11, 2005 Report Share Posted December 11, 2005 A snubber capacitor is used so that a fast-rising voltage doesn't cause the thyristor to turn-on. A thyristor has a dv/dt rate-of-voltage-rise rating that it can withstand without turning on. A snubber capacitor slows-down the voltage rate-of-voltage-rise.

prateeksikka Posted December 13, 2005 Report Share Posted December 13, 2005 Actually we generally use a series combination of a resistor and a capacitor which is known collectively as a snubber circuit.It protects the thyristor.I guess cap alone will not even work!
