| What is the frequency converter？ |
| | Inverter (Variable-frequency Drive, VFD) is the application of frequency conversion technology and microelectronic technology, electrical control equipment by changing the motor power frequency to control AC motor. The inverter is mainly composed of a rectifying (AC to DC), filtering, inverter (DC to AC converter), braking unit, unit, detection unit driven micro processing unit etc.. The inverter by internal IGBT open to adjust the output voltage and frequency of the power supply, the power supply voltage needed to provide according to the actual needs of the motor, so as to save energy, the purpose of speed, in addition, the inverter has many protection functions, such as over-current, over-voltage, overload protection, etc.. With the development of industrial automation, the inverter is widely applied. | | | author: Published at: 2013/4/28 15:29:36 |  |
