Dynamic Braking in Variable frequency Drives
Dynamic braking is the method of stopping the motor by dissipation of heat in the resistor. When VFD drives a motor, the motor acts as
VF drive
VVVF Drive- Why V/f Ratio is Kept Constant in VFD?
VVVF( Variable voltage variable frequency) control is used to control the speed of the induction motor. The VVVF drive controls the voltage and frequency simultaneously
