I am looking for any help with the design of RC snubber circuit for the three phase thyristor bridge rectifier. The thryistors (SCRs) undergo reverse recovery process during turnoff and hence they experience huge voltage spikes (or overvoltages) if snubbers are not used. Are there any design procedures available in designing the RC snubber circuits for such a rectifier configuration.
Thanks in advance.
