Firstly, the function of Mitsubishi inverter
Mitsubishi inverter integrates high-voltage and high-power transistor technology and electronic control technology, and is widely used. The function of the Mitsubishi inverter is to change the frequency and amplitude of the AC motor power supply, thus changing the period of its moving magnetic field to achieve the purpose of smoothly controlling the motor speed. The emergence of Mitsubishi frequency converter simplifies the complicated speed control. The combination of Mitsubishi frequency converter + AC squirrel cage induction motor replaces most of the work that can only be done with DC motors, reduces the volume and reduces the maintenance rate. Make the transmission technology develop to a new stage.
Secondly, the composition of Mitsubishi inverter
Mitsubishi inverters are usually divided into 4 parts: rectifier unit, high-capacity capacitor, inverter and controller.
1 The rectifier unit converts alternating current with a fixed operating frequency into direct current.
2 High-capacity capacitors store the converted electrical energy.
3 The inverter is composed of high-power switch transistor arrays to form electronic switches, which convert direct current into square waves of different frequencies, widths and amplitudes.
4 The controller works according to the set program to control the amplitude and pulse width of the output square wave, so that it is superimposed into an alternating current similar to a sine wave to drive the alternating current motor.
