What is Variable Frequency Drive Overview about?
This document provides information about variable frequency drives (VFDs). It discusses what a VFD is, how it works to control the speed and torque of AC induction motors by varying the frequency and voltage supplied to the motor. A VFD allows AC motors to operate at variable speeds by converting fixed line voltage and frequency to adjustable voltage and frequency. It does this using pulse width modulation (PWM) technology to control insulated gate bipolar transistors (IGBTs) that rapidly switch the supply
