What is VVVF Drive ?..

Answer / sandeep vazhoor

VVVF drive(also called VVVF Inverter) is a power electronic
controller used to control the speed of 3 phase AC Motors
(synchronous or induction) by varying the frequency and
voltage applied to the motor terminals. Voltage and
frequency relationship is decided based on the motor name
plate data and the load characteristics.

Advantages of VVVF Drives are –

a) Stepless speed can be achieved which is required in
process control.

b) Energy Saving.

c) Improvement in productivity.

d) Process improvement and better quality of the product.
