| 变频器（VFD）是应用变频技术与微电子技术，通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。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。 Frequency converter (VFD) is the application of frequency conversion technology and microelectronics technology to control the AC motor's power control equipment by changing the frequency of the motor's power supply. Frequency converter is mainly composed of rectification (AC variable DC), filtering, inverter (DC to AC), brake unit, drive unit, detection unit, micro processing unit and so on. The inverter adjusts the voltage and frequency of the output power by the interruption of the internal IGBT, and achieves the purpose of energy saving and speed regulation according to the electricity. In addition, the inverter has many protection functions, such as over current, over voltage, overload protection, etc. |
