![]() ![]() While current switching is everywhere, snubbers will generally only be required where a major current path is switched, such as in power supplies. Inductive elements are often unintentional, arising from the current loops implied by physical circuitry like long and/or tortuous wires. The snubber provides a short-term alternative current path around the current switching device so that the inductive element may be safely discharged. Additionally, if the voltage generated across the device is beyond what the device is intended to tolerate, it may damage or destroy it. This transient can be a source of electromagnetic interference (EMI) in other circuits. 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. JSTOR ( April 2011) ( Learn how and when to remove this template message)Ī snubber is a device used to suppress (" snub") a phenomenon such as voltage transients in electrical systems, pressure transients in fluid systems (caused by for example water hammer) or excess force or rapid movement in mechanical systems. ![]() Unsourced material may be challenged and removed.
