A snubber is a circuit that is used in semiconductor devices for protection and performance enhancements. ... A snubber circuit limits or stops (snubs) switching voltage amplitude and its rate of rise, therefore reducing power dissipation.
What is the function of snubber?
Snubber circuits are essential for diodes used in switching circuits. It can save a diode from overvoltage spikes, which may arise during the reverse recovery process. A very common snubber circuit for a power diode consists of a capacitor and a resistor connected in parallel with the diode as shown in Fig.
How does snubber circuit work?
In the RC snubber circuit, the resistance R limits the discharge current of capacitor at the instant of firing of SCR. Before SCR is fired, capacitor C charges to full voltage V. If SCR is fired, when the capacitor voltage is maximum, it discharges through the local path formed by capacitor C, Resistance R and SCR.
