Variable Frequency Drives Explained by Manjiri Phadnis is a document available to read on EtoBox.
A variable frequency drive (VFD) controls the speed of an electric motor by varying the frequency of the power supplied to the motor. A VFD consists of a rectifier, DC bus, and inverter. The rectifier converts AC power to DC, which is smoothed by the DC bus and then converted back to AC by the inverter at a variable frequency to control motor speed. Motor speed is directly proportional to the frequency output by the VFD.
