Paul Rako at Electronic Design’s article describes snubber capacitors functionality to reduce the spikes in converter design, protecting the transistors and reducing EMI. The article also provides some recommendations on snubber capacitor type selection. A snubber circuit limits voltage spikes in power converters.
The high stability of capacitance of polypropylene capacitors makes them a suitable option for snubber applications. Snubber circuits subject components to extremely high voltage transients and demand components that can withstand high voltages.
Mica capacitors are suitable for low pulse applications. Switchers produce potentially harmful voltage spikes that can damage electronic components. Snubbers are used in power circuits to suppress harmful voltage transient spikes.
Purpose of Snubber Circuit The main purpose of Snubber Circuit is to prevent the unwanted triggering of SCR or thyristor due to high rate of rise of voltage i.e. dv/dt. We already know that if the rate of rise of anode to cathode voltage of SCR is high then it may lead to false triggering. This is commonly known as dv/dt triggering.
When designing a snubber circuit, consider the following: Power Rating: Ensure the resistor can handle the power dissipated during transients. Capacitor Voltage Rating: The capacitor should be rated for a voltage higher than the expected transient voltage.
Snubber circuits subject components to extremely high voltage transients and demand components that can withstand high voltages. Polypropylene capacitors can withstand high voltages, and components with operating voltage ratings of 1 kV, 2kV, 3kVand above are commonly available.

Snubbers are frequently used in electrical systems with an inductive load where the sudden interruption of current flow leads to a large counter-electromotive force: a rise in voltage across the current switching device that opposes the change in current, in accordance with Faraday''s law.
