1.1 Overview

Through relevant experiments, the inverter of this training device can help students become familiar with the use of various industrial control components, master their control principles and methods, and cultivate students' corresponding knowledge and skills. It is suitable for higher vocational schools, junior colleges, secondary vocational schools and technical schools. Teaching and skills training assessment in related majors.
Frequency converter (Variable-frequency Drive, VFD) is a power control device that applies microelectronics technology and frequency conversion technology to control the speed and other performance of AC motors by changing the frequency of the power supply when the motor is working.
The frequency converter hanging box is an electrical device mainly used to control the frequency conversion speed regulation of AC motors. It adjusts the speed of the motor by changing the frequency of the power supply, thereby achieving precise speed control and energy saving
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 inverter relies on the switching of the internal IGBT to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual working environment and working needs of the motor, thereby achieving the purpose of adjusting the speed of the motor. In addition, the frequency converter also has some protection functions for the motor, such as overcurrent, overvoltage, overload protection, etc.
