"Power Quality Improvement & Regenerative Unit"
Active Front-end Converter is an IGBT based AC to DC converter. It keeps supply side power factor to unity and supply current sinusoidal. Our Axpert-i-Sine Series AFC is also capable of feeding back the excessive power from DC link capacitor to grid side and so it is also popularly known as Regenerative Unit. A single unit of high capacity can also be used for multiple VFD (Variable Frequency Drive) of low capacity having common DC bus configuration.
Six pulse diode rectifier bridge is a basic building block of many products such as UPS, battery chargers, VFDs, DC drives etc., known as non-linear loads. They generate about 70…120% current harmonic distortion at the input depending upon the source impedance.
AFC reduces current harmonic distortion level to <5%. It is a high quality product and easily meets the international power quality standards such as IEEE 519-2014.
