Basic Concepts of ABB AC VFD Drives
ABB AC VFD drives are comprised of two main components: a power converter and a control unit. The power converter changes the AC power from the mains supply into variable frequency AC power. The control unit then uses this variable frequency AC power to control the speed and torque of the motor.
| Concept | Description |
|---|---|
| PWM (Pulse Width Modulation) | A technique used to generate variable frequency AC power. |
| Closed-loop control | A method of controlling the motor's speed and torque using feedback from the motor. |
| Vector control | A high-performance control technique that provides precise motor control. |
