Infeed 1
1.1 Active Infeed
1.1.1 Introduction
General
Note
Line Modules (Active Line Modules, Basic Line Modules, Smart Line Modules) of different
types must not be operated simultaneously on the same DC link.
Features
● Controlled DC link voltage whose level can be adjusted (independent of line voltage
fluctuations)
● Regenerative feedback capability
● Specific reactive current setting
● Low line harmonics, sinusoidal line current (cosφ = 1
Description
Active Infeed closed-loop control works in conjunction with the line reactor and the Active
Line Module as a step-up converter. The level of the DC link voltage can be defined through
parameters, and, by means of the control, it is independent of line voltage fluctuations.
The open and closed-loop control firmware for the Active Line Module runs on the Control
Unit assigned to it. The Active Line Module and Control Unit communicate via DRIVE-CLiQ.
