Snubber circuit is used to protect SCR from $d_v/d_t$ turn ON.

A snubber circuit consists of a series combination of resistance $R_s$ and capacitance $C_s$ in parallel with the thyristor as shown in figure.

When forward voltage is applied across the thyristor capacitor $C_s$ charges slowly and prevents sudden rises …
