Hi Max,
short circuit is required in all the applications where external influences can harm the 'normal' functional behavior of the power electronic system.
As an example, in three-phase motor drives applications, the failure of the motor winding insulation can create a short between the phases, or a failure between a phase and the motor casing that is connected to earth.

A good explanation of the meaning of the short circuit can be found at the section 2.3 of this application note: https://www.infineon.com/dgdl/Infineon-AN_201814_Trenchstop_1200V_IGBT7-AN-v01_00-EN.pdf?fileId=5546....

Regards,
Giuseppe
