| 变频器主要由整流（交流变直流）、滤波、逆变（直流变交流）、制动单元、驱动单元、检测单元微处理单元等组成。变频器靠内部IGBT的开断来调整输出电源的电压和频率，根据电机的实际需要来提供其所需要的电源电压，进而达到节能、调速的目的，另外，变频器还有很多的保护功能，如过流、过压、过载保护等等。随着工业自动化程度的不断提高，变频器也得到了非常广泛的应用。 Frequency converter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, microprocessor unit of detection unit, etc. Frequency converter adjusts the voltage and frequency of output power supply by interruption of internal IGBT, and provides the required power supply voltage according to the actual needs of motor, thus achieving the purpose of energy saving and speed regulation. In addition, frequency converter also has many protective functions, such as over-current, over-voltage, over-load protection and so on. With the continuous improvement of industrial automation, frequency converter has also been widely used. |
