Snubber network design of Snubbers for Power Circuits, Snubbers are circuits which are placed across semiconductor devices for protection and to improve performance, reduce or eliminate voltage or current spikes, limit dI/dt or dV/dt, shape the load line to keep it within the safe operating area (SOA), transfer power dissipation from the switch to a resistor or a useful load, reduce total losses due to switching, reduce EMI by damping voltage and current ringing, pdf file

Snubber network RC snubber networks For thyristor power control and transient suppression, RC networks are used to control voltage transients that could falsely turn-on a thyristor. These networks are called snubbers. The simple snubber consists of a series resistor and capacitor placed around the thyristor. These components along with the load inductance form a series CRL circuit. Snubber theory follows from the solution of the circuit’s differential equation, pdf file
