The Protection of Thyristor in Motor Control System
The bearing ability of thyristor to over-voltage and over-current is poor. According to the causes lead to over-voltage and over-current , adopting over-voltage protection such as RC snubber, vristor, and so on, and limiting reactors, current sensing devices, fast fuses, etc. are used in fast over-current protection.
