Preface
Description of Operation
The PowerFlex Active Front End is a regenerative DC bus supply that is used to
supply DC power to a lineup of common DC bus drives, or one common bus
drive. The AFE uses a pulse width modulated (PWM)-controlled IGBT
converter to allow bi-directional power flow to the AC line.
show examples of the AFE powering a lineup of PowerFlex 755 drives
and the AFE powering one PowerFlex 755 drive. For additional information
and bus conditioning requirements, see Drives in Common Bus
.
