AN1048D - RC Snubber Networks
AN1048/D RC Snubber Networks For Thyristor Power Control and Transient Suppression By George Templeton Thyristor Applications Engineer http://onsemi.com APPLICATION NOTE INTRODUCTION Edited and Updated 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.
