Variable-frequency drive - Wikipedia
The VFD controller is a solid-state power electronics conversion system consisting of three distinct sub-systems: a rectifier bridge converter, a direct current (DC) link, and an inverter.

Variable Frequency Drive: Definition, Working, and Applications
A variable frequency drive (VFD) is a device that controls the speed and torque of an AC motor by adjusting the frequency and voltage of the power supply. A VFD can also regulate the acceleration and deceleration of the motor during start-up and stop, respectively.

What is a Variable Frequency Drive? - VFDs.com
A variable frequency drive (VFD) is a type of motor controller that can adjust the speed of an AC electric motor. It does this by varying the frequency and voltage supplied to the motor.

VFD (Variable Frequency Drive) - Working, Types & Applications
What is a VFD? VFD stands for Variable Frequency Drive. As its name suggests it is an adjustable frequency drive that varies the frequency of the AC supply. Since the speed of an induction motor depends on the supply frequency, the VFD can be used to vary its speed.
