Variable frequency drive (VFD) is a power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's operating power supply.
The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, driving unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by disconnecting the internal IGBT, providing the required power supply voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection, etc.
Sincerity Technology provides a complete range of capacitors with stable quality for Variable-frequency Drive.
