What is a variable frequency drive?

A variable frequency drive is an electronic device that can convert alternating current (AC) of a fixed frequency into AC with adjustable frequency and voltage, thereby controlling the speed and torque of an electric motor. It mainly consists of a rectifier that converts AC into direct current (DC). After voltage stabilization in the DC link, an inverter then converts the DC back into AC with the required frequency and voltage. It is widely used in industries, heating, ventilation, and air - conditioning (HVAC) systems, the automotive sector, etc., to achieve motor speed regulation, energy conservation, and precise operation control.
