The frequency converter is a power control device that controls the Ac motor by changing the working frequency of the motor byapplyingfrequency conversion technology and microelectronic technology.
The freguency converter is mainly composed of rectification (AC to Dc), filtering, inverter (Dc to Ac), braking unit, drive unit, anddetection unit micro processing unit. The inverter adiusts the voltage and frequency of the output power supply by the breakingofthe internal lGBT, and supplies the required power supply voltage according to the actual needs of the motor, thereby achievingthe purpose of energy saving and speed regulation, in addition, the freg uency converter has many protection functions. such asovercurrent, overvoltage, overload protection and so on. With the continuous improvement ofindustrial automation, invertershave also been widely used.
