AC Line Tuning
PowerFlex® 755T regenerative and low harmonic AFE products have parameters
that tune the converter to the AC supply. Tuning lets the converter work reliably
with a wider range of supplies. You can also configure the converter to switch
between two different supplies, which supports the use of backup generators
without having to reconfigure the system.
Technical Overview
The goal of tuning the PowerFlex 755T converter is to obtain a robust bus supply
that provides protection against under voltage and over voltage conditions
without causing resonance or instability. In addition,
• The converter can be configured for two AC line sources to facilitate the
use of a backup generator.
• The robust default current regulator and voltage regulator bandwidths
work well in most installations.
• Gains automatically adjust to the line impedance of two different AC line
sources.
• The converter can switch between AC line sources with limited
interaction.
– Via HIM, Connected Components Workbench™ software, and
Datalinks – all versions
– Digital Input – firmware revision 4 and later
• The converter tuning capabilities and features of PowerFlex 755T
products accommodate one AC line source or a primary source with a
backup generator.
