B.5.3 9 Cell Output Filter, Inductance
9-Cell Output Filter. Inductance
When the VFD requires the SYNC TRANSFER feature, the output of the drive is equipped
with a reactor and switchgear (contactors). These reactors cannot be packaged into the core
configuration due to space limitations; therefore, they are housed in transition cabinets. These
reactors limit the rate of rise of current during transfers if the line voltage and drive output
voltage amplitude, frequency, and phase angle do not exactly match. Table "9-Cell Output
Filter Inductance" lists the required inductance for SINAMICS PERFECT HARMONY GH180
synchronous transfer reactors. These reactors are typically custom engineered, and may
include an overload rating that matches the cell type and two sets of thermal protectors
embedded into the windings. They are sized, based upon the continuous current rating of the
power cells and maximum voltage available of the drive.
