Definition

Variable-frequency Drive (VFD) is a power control device that uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power supply frequency of the motor. The inverter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), brake unit, drive unit, detection unit and micro-processing unit. The inverter depends on the internal IGBT to adjust the output power supply voltage and frequency, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed regulation, in addition, the inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, the frequency converter has also been widely used. Through the use of high-density device structure design and advanced ultra-thin chip processing technology, the IGBT series products are introduced, which significantly reduce the saturation voltage drop and turn-off loss of the device by optimizing the carrier injection efficiency and carrier distribution, thereby reducing the device power consumption and improving the system efficiency.
