High-current test bench

  Copyright: © PGS Set up of Test Circuit

The high current test bench allows quantifying the effects of high currents on thyristor-based power semiconductors by load tests and allows emulating different scenarios in a controlled environment. The test bench is capable of generating symmetrical and asymmetrical sinusoidal currents of up to 20 kA with a maximum duration of two seconds.

Therefore, thyristor-based power semiconductors can be tested for their ability to switch high currents and block high voltages before they are used in converters (e.g. FACTS) for high power applications. As a result, thyristor-based converters can be safely integrated into the grid to stabilize distribution and transmission networks. Figure 1 shows the setup of the high current test bench for thyristor-based power semiconductors.
