Description
hardware flow control. It is an ideal choice in the field of industrial automation.
[Introduction] PLC and frequency converter are two important electrical equipment in the field of industrial automation control. This book
combines the introductory knowledge of PLC and frequency converter. The main contents include introduction to PLC, PLC composition and
principle, and the use and application of PLC programming software. System development, basic instructions and applications, step instructions
and applications, functional instructions and use, the structure and principle of the frequency converter, the use of the frequency converter, as well as
the selection, installation and maintenance of the frequency converter.
What is a frequency converter ? Generally speaking, it is: AC – DC – AC (it can also be said to be rectifier first – then inverter). The frequency converter
that undergoes this process is also called AC-DC-AC frequency conversion. Currently, it is also used in various industries. One of the more commonly
used ones. In addition, there is also an AC-AC conversion, which is also called an AC converter.
1. What is a frequency converter?
Frequency converter is a power control device that uses the on-off function of power semiconductor devices to convert industrial frequency power into
another frequency. The frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit, microprocessing unit, etc.
The frequency converter is a device that converts industrial frequency power supply (50Hz or 60Hz) into AC power supply of various frequencies to
realize variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the AC
power into DC power. The DC intermediate The circuit smoothes and filters the output of the rectifier circuit, and the inverter circuit reverses the DC
power into AC power. For inverters that require a lot of calculations, such as vector control inverters, sometimes a CPU for torque calculation and some
corresponding circuits are needed. Variable frequency speed regulation achieves the purpose of speed regulation by changing the frequency of power supply to the motor stator winding.
