Breakover diode (BOD) has become a commonly used solution for thyristor overvoltage protection owing to its excellent volt-ampere and temperature characteristics. At present, high-voltage BOD is mainly monopolized by some foreign companies. To solve the bottleneck problem, a high-speed overvoltage triggering circuit without BOD is proposed, which uses a high-speed signal processing and amplification circuit consisting of components such as operational amplifiers and output transformer less (OTL) complementary symmetric amplification circuits to achieve fast overvoltage detection and protection. Finally, an experimental platform of 1 200 V thyristor overvoltage triggering circuit was built in the laboratory. Moreover, a comparison with the BOD triggering scheme fully verified the accuracy, speed and reliability of the proposed scheme.
