What does VVVF stand for?
Answer: D
VVVF stands for variable voltage variable frequency.
An induction motor's speed is proportional to the supply frequency, so a VVVF drive varies the frequency to control speed, and varies the voltage with it to keep the magnetic flux constant. It is used in lifts, trains and industrial drives.
