DC-link reactor

The DC link reactor decouples the line-side converter from the motor-side converter and
smoothes the direct current. In the event of a fault with overcurrent, the DC link reactor limits the
rate of current rise with its inductance, together with the line reactors. Each DC link reactor
consists of two magnetically coupled windings wound on an iron core.

AVT combination module

The AVT combination module (Actual Value Transmission) processes signals for sensing the
actual current and voltage values. The AVT combination module converts analog signals into
digital signals. Then the module transfers the signals to the Power Stack Adapter (PSA). The
signals are transferred to the PSA via fiber-optic cables.
