The thyristor T901N in the Sinamics SL150 datasheet indicates constant operation limits based on temperature. In the datasheet, the continuous operation limits for this thyristor are as follows:
Current 940A at 85°C Current 1160A at 70°C Current 1350A at 55°C
This means that if you control the thyristor T901N at a current of 940A, the operational temperature should not exceed 85°C. If the current is 1160A, the operational temperature should not exceed 70°C, and if the current is 1350A, the operational temperature should not exceed 55°C.
The question here is whether anyone knows how controlling currents of 940A, 1160A, or 1350A would affect the temperature rise and cause continuous operation limitations based on the temperature restriction?
