Overview

Low voltage frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power supply frequency of the motor.

The inverter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, detection unit and micro-processing unit. The inverter depends on the internal IGBT to adjust the output power supply voltage and frequency, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed regulation, in addition, the inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, the frequency converter has also been widely used.
