Even if only single IGBTs are tested, all the system’s gate drivers must be supplied with energy.
All the other IGBTs are then kept in the off state by applying negative gate voltages. This is
particularly important when switching the IGBTs under test.
The short-circuit behavior can also be verified at this point.
The system is then ready to start under real-world load conditions. This allows the thermal behavior of the
whole arrangement to be determined.
The system must be re-qualified over the entire specified range of temperature and load conditions.
CAUTION: All handling with high voltages involves risk to life.
It is imperative to comply with the respective safety
regulations!
