2.3 ABOUT THE CFW-11 RB

The regenerative frequency converter is a bidirectional three-phase boost type AC/DC converter that generates
higher DC voltage than the line peak voltage. These converter are commonly known as AFE (Active Front End)
drives. The CFW-11 RB line utilizes the "RB" sulfix which states for Regenerative Braking because it has the natural
capacity of allowing the energy to flow from the converter to the power supply when the motor is braking. The DC
voltage generated by the regenerative converter is used to feed other converter power units that are controlling
three-phase motors.
The CFW-11 RB regenerative converter is a high performance product that allows three-phase power supply
rectification with the following advantages:
Low input current harmonic distortion.
„
Capacity of recovering energy back to the power supply (regeneration) allowing high braking torque levels.
