Review of Thyristor Junction Temperature Calculation Methods

Abstract:

The thyristor has been widely used in many fields since it has been invented, and has promoted the development of the DC transmission technology rapidly. The increasing temperature of its junction may cause serious hazards. Because of this, a variety of methods that can obtain the junction temperature has been summarized in this paper, such as the indirect measurement method, the direct measurement method, the equivalent thermal impedance network method and the numerical calculation method, etc. Summaries have been made in different occasions which these methods were applied. It also compared the advantages and disadvantages of each method and pointed out the developing trends and researching directions in the future.
