Shared AC/DC Hybrid Configurations
In shared AC/DC hybrid configurations, three-phase AC input power is
supplied to two or more (leader) drives that act as converters. This parallel
converter configuration increases the DC power supplied to the inverter
(follower) drives:
• The leftmost drives in a hybrid configuration act as parallel converter
drives and must be of the same power rating (catalog number).
• Shared DC (inverter) drives mounted to the right of the shared AC/DC
(converter) drives must have the same or lower power rating (catalog
number) than the shared AC/DC drives.
• The total motoring load must not exceed the rated load for the drives
sourcing the DC power. Each follower drive must be sized for the motor
load connected to it.
• Total available converter power is derated by 30%.
• The maximum number of drives configured in the project file as
Shared AC/DC is restricted according to Table 80 on page 220
.
• The maximum number of drives configured in the project file as
Shared DC is restricted according to Table 79 on page 219
.
• Shared AC/DC hybrid configurations support Bulletin 2198 capacitor
modules.
