Abstract

In order to verify that the thyristor can withstand the maximum junction temperature required by the design and high and low temperature cyclic stress

the valve temperature rise test shall be carried out in the factory test stage. First

the calculation method of temperature rise test parameters is introduced. Then the electrical circuit of temperature rise test using DC current heating principle are designed. Finally

the temperature rise test parameters are calculated with an example of a valve

and the temperature rise test is carried out in the laboratory. The test results show that the test values and calculated values of the temperature rise test parameters are basically the same

and the performance of thyristor did not decrease before and after temperature rise test. The results show that the temperature rise test can be completed by combining the calculation method of temperature rise test parameters and the temperaturerisetestloop

and the temperature rise performance of the thyristor can be verified.
