Snubber Resistor. Snubbers are circuits which are placed across semiconductor devices for protection and to improve performance. The design procedure is as follows.
The resistor selected must be non inductive since it must handle very high frequen cies. In an electrical system where there is a sudden interruption of current flow there can be a corresponding significant rise in voltage across the device. Using all of the calculated values the design for the power supply switch snubber is complete and can be implemented in the application.
The power dissipation on r snub at a given switching frequency f s is.
Power semiconductors are the heart of power electronics equipment. They suppress voltage spikes that could damage sensitive electronic components. Snubbers are circuits which are placed across semiconductor devices for protection and to improve performance. It does this by limiting the rate of rise in voltage dv dt across the thyristor to a value which will not trigger it an appropriately designed rc snubber can be used with.
