Snubber circuit design methods - Rohm
produced during the overvoltage, it means the snubber doesn’t discharge all energy stored in C SNB at every switching transient. Thus the energy consumption at R SNB does not much increase at high switching frequencies. Therefore a large C SNB can be implemented, which realizes a highly effective snubber circuit.
