Introduction of frequency converter
The frequency converter is a power control device that uses frequency conversion technology and
microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit,
drive unit, a detection unit, and micro-processing unit.
The inverter adjusts the voltage and frequency of the output power supply by opening and closing the internal IGBT,
and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the
purpose of energy-saving and speed regulation. In addition, the inverter has many protection functions.
Such as overcurrent, overvoltage, overload protection, and so on. With the continuous improvement of industrial automation,
frequency converters have also been widely used.
