1.1.1Introduction

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.
