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.

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
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.

Variable Frequency Drive: Definition, Working, and Applications
What is a Variable Frequency Drive? A VFD is a complete drive module that converts input power into controlled AC for a motor. Frequency sets synchronous speed, while the control algorithm regulates voltage and current to produce the required flux and torque within drive and motor ratings.
