Gelite inverter effect

格立特变频器

Inverter integrates high voltage high power transistor technology and electronic control technology, and has been widely used. The function of frequency converter is to change the frequency and amplitude of AC motor power supply, so as to change the period of its motion magnetic field, and achieve the purpose of smoothly controlling motor speed. The emergence of frequency converter simplifies the complex speed control. The combination of frequency converter and AC squirrel cage induction motor replaces most of the original work which can only be done by DC motor, reduces the volume, reduces the maintenance rate and develops the transmission technology to a new stage.


Working Principle of Gelite inverter


Frequency converter is a power control device that converts power supply into another frequency by using the on-off function of power semiconductor devices. It can realize the functions of soft starting, frequency conversion speed regulation, improving operation accuracy, changing power factor, over-current/over-voltage/over-load protection for AC asynchronous motor. So as to improve the product process, energy saving and environmental protection functions.
