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. With the help of snubber circuit the false turn on of a thyristor due to large dv dt can be prevented.
The saturating reactor offers a high inductance at low current and a low inductance at high currents. A snubber is a circuit that is used in semiconductor devices for protection and performance enhancements. A dc grading resistor r g distributes the direct voltage across the different thyristor levels.
The saturating reactor offers a high inductance at low current and a low inductance at high currents.
It is also used as a voltage divider to measure the thyristor level voltage. The saturating reactor offers a high inductance at low current and a low inductance at high currents. With the help of snubber circuit the false turn on of a thyristor due to large dv dt can be prevented. This type of snubber circuit consists of a series combination of resistance r and capacitance c in parallel with a scr.
