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 ponents along with the load inductance form a series CRL circuit. Snubber theory follows from the solution of the circuit’s differential equation. Many RC binations are capable of providing acceptable performance. However, improperly used snubbers can cause...
