Beijing Xiaotangshan converter repair, frequency counters installation, sales, deep well pump to mention, drop. Inverter (Variable-frequency Drive, VFD) is the application of inverter technology and microelectronic technology, by changing the motor means to control the power supply frequency AC motor power control equipment. Inverter is mainly by the rectifier (AC to DC), filter, inverter (DC-AC), braking unit, drive unit, a detection unit micro processing unit and other components. IGBT inside the inverter by breaking to adjust the output voltage and frequency power supply, according to the actual needs of the motor to provide power supply voltage it needs, thus achieving the purpose of energy, speed, and in addition, there are a lot of drive protection , such as overcurrent, overvoltage, overload and so on. With the continuous improvement of industrial automation, the drive has been very widely used.
