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. A VFD consists of three main components: a rectifier, an inverter, and a control system.
