Variable Frequency Inverter For Industrial Use

what is variable frequency drive ?

Variable-frequency drive (VFD) is a power control device that controls the AC motor by changing the working frequency of the motor by applying variable frequency technology and microelectronic technology. 

The variable frequency drive is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, and detection unit micro processing unit. The inverter adjusts the voltage and frequency of the output power supply by the internal IGBT breaking, and supplies the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation.

In addition, the variable frequency drive has many protection functions. Such as overcurrent, overvoltage, overload protection and so on.

Working principle

AC-DC-AC inverter is the first to convert the power frequency AC into a DC through the rectifier, and then convert the DC into an AC with adjustable frequency and voltage. It is also called an indirect inverter. It is a general-purpose inverter widely used at present.
