2.3 ABOUT THE CFW-11M 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-11M 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
inverter power units that are controlling three-phase motors.

The CFW-11M 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.

The CFW-11M RB line presents a modular structure with the possibility of assembling up to five power units
(UP11 - Books), one control unit (UC11) and interconnection cables. The control unit (UC11) is able to
control up to 5 (five) UP11’s.

The UP11 are directly feed via DC link bus bar and the UC11 is fed via the +24 Vdc power supply. Figure
2.1 shows an application sample.

The UP11 power units control is done by the UC11 control unit. The control unit is composed by the CFW-11M
RB control rack line, the IPS1 board and the CSR11 synchronism board. The IPS1 board exchange signals
with all UP11 units. The CSR11 synchronism board supervises the power supply, measuring the voltage values
and synchronizing the control.
