The official definition of the inverter: inverter (variable frequency drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor power frequency way to control AC motor power control equipment.
Further explanation: the inverter is based on the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed regulation, but also over current, over voltage, overload protection, etc..
