Frequency converter, the full name of variable frequency governor, is an electric power control device that applies frequency conversion technology and microelectronic technology to control AC motor by changing the frequency of motor working power supply.
The frequency converter is mainly composed of rectifier (AC to DC), filter, inverter (DC to AC), braking unit, driving unit, detection unit and microprocessor unit.
Inverter is one of the driving and controlling equipment of three-phase motor, which plays an important role and is indispensable in the field of industrial automation.
