APPLICATIONS CONCLUSION 3. A Variable Frequency Drive (VFD) is a
type of motorcontroller that drives an electric motor by varying
thefrequency and voltage supplied to the electric motor. A variable
frequency drive is an adjustable speeddrive. VFDs are available in
a number of different low andmedium voltage AC-AC and DC-AC
topologies. Other names for a VFD are variable speeddrive,
adjustable speed drive, adjustable frequencydrive, AC drive, micro
drive, and inverter. 4. Before semiconductor devices were
