3.2.19

Failure of a power semiconductor module

Fundamentals
The power section must shut down if a power semiconductor module fails. The failure is
simulated by withdrawing the fiber-optic cable connector from the gating module of a power
semiconductor module. This interrupts the control.
Test procedure
1. The auxiliary voltage is present.
2. The fiber-optic cable connector of a gating module is withdrawn.
