Snubber Circuit: A Safeguarding Circuit for Protecting Against

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. This transient can be a source of electromagnetic interference (EMI) in other circuits. Additionally, if the WebAs explained earlier, SB or SA should be triggered only when DR2 or DR1 is OFF.
