Abstract
The voltage stress caused by turn-off of HVDC thyristor valve is one of the important research objects about its electric characteristics. In this paper, the circuit model proposed in reference for the analysis of turn-off voltage stress was improved and its application range was also widened. Furthermore, Laplace equations about turn-off voltage stress were deduced and a detailed analysis was also performed. The changes of turn-off voltage stress under different application circumstances and those with different circuit parameters were obtained and key factors were also summed up. From the computation and simulation results, it was concluded that the analytical method is available and its computational results are comparatively precise.
