Inverter/Inverter dan Konverter / variable frequency drive / variable speed drive is a motor speed control device by changing the value of the frequency and voltage that enters the motor. setting the value of the frequency and voltage is intended to get the desired rotation speed and motor torque as needed. In simple terms, the basic principle of an inverter is to be able to change the frequency to be smaller or bigger, namely by changing the AC voltage to DC voltage and then turning it intoAC voltage again with a different or adjustable frequency.
