    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.
