What is a pump Inverter?

What is a pump Inverter? Generally speaking, it is: AC-DC-AC (or rectification first-then inverter). The pump Inverter that undergoes this process is also called AC-DC-AC frequency conversion, and it is also in various industries. One of the more used. In addition, there is a kind of AC-AC conversion, which is also called AC-AC converter.

The pump Inverter is an electric energy control device that uses the on-off action of power semiconductor devices to transform the industrial frequency power supply into another frequency. The pump Inverter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions. , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, pump Inverters have also been widely used.

Inverter is a device that converts industrial frequency power (50Hz or 60Hz) into AC power of various frequencies to achieve variable-speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts AC power into DC power. The circuit smoothes and filters the output of the rectifier circuit, and the inverter circuit reverses the direct current into alternating current. For pump Inverters such as vector control pump Inverters that require a large amount of calculations, sometimes a CPU for torque calculation and some corresponding circuits are needed. Frequency conversion speed regulation is to achieve the purpose of speed regulation by changing the frequency of the motor stator winding power supply.
