Snubber Circuit In Power Electronics. Snubbers are frequently used in electrical systems with an inductive load where the sudden interruption of current flow leads to a sharp rise in voltage across the current switching device inductive kick in accordance with faraday s law this transient can be a source of electromagnetic interference emi in other circuits. Advertised as such many snubbers are in fact a means to switch a device more softly and the transition from snubbers to soft switching circuits is a gradual one.
Many soft switching circuits use principles common in snubbers with additional modification of the overall circuit added. Due to the availability of alternative solutions snubbers are less common today than they once were. Additionally if the voltage generated.
With the help of snubber circuit the false turn on of a thyristor due to large dv dt can be prevented.
Advertised as such many snubbers are in fact a means to switch a device more softly and the transition from snubbers to soft switching circuits is a gradual one. The scr snubber circuit is mainly used to protect the device from large rates of change of anode to cathode voltage and anode current. The saturating reactor offers a high inductance at low current and a low inductance at high currents. A saturating reactor is used to protect the valve from di dt stresses during turn on.
