Variable frequency drive (VFD) is a power control device that integrates frequency conversion technology and microelectronics technology. It is used to convert fixed frequency AC power into adjustable frequency AC power, thereby achieving precise control of AC motors.

• Vector control technology: By measuring and controlling the stator current vector of asynchronous motors, independent control of motor torque and magnetic field is achieved, improving speed regulation accuracy and dynamic response performance.
• Direct Torque Control (DTC): Control the motor directly in the stator coordinate system, without the need for complex vector transformations, with fast response speed and high control accuracy.
• Matrix AC-AC frequency conversion technology: eliminates the intermediate DC link, achieves a power factor of 1, sinusoidal input current, and four quadrant operation capability, and improves system power density.
