AC Motors, Controllers, and Variable Frequency Drives

A Current Source Inverter (CSI) is a type of variable frequency drive (VFD) which converts incoming AC voltage and varies the frequency and voltage supplied to the AC Induction Motor. The general configuration of this type of VFD is like that of other VFDs in that it consists of a Converter, DC Link, and Inverter. The converter...

How an Inverter Drive Works and Controls the Speed of an AC ...

An Inverter Drive (VFD) works by taking AC mains (single or three phase) and first rectifying it into DC, the DC is usually smoothed with Capacitors and often a DC choke before it is connected to a network of Power Transistors to turn it into three phases for the motor. The network of Power Transistors of a small Inverter drive...

DESIGN OF INVERTER DRIVE FOR AC INDUCTION MOTOR.pdf

induction motor drive's cost comes from the inverter and its controller. A principle of v/f control of the output voltage in PWM voltage-source inverters is described. The proposed approach is a modification of the sinusoidal modulation technique, and consists of open-loop control of three-phase inverter fed induction motor that...

Why are rectifiers-inverters used to drive AC motors instead of ...

DC motors have effectively one variable: how much power are you feeding the motor? AC motors have two variables: power, and frequency. I'm not an expert in motors, but I'd expect that AC motors would thus allow independent control of speed and torque, while DC motors do not. Directional control is...
