Active Harmonic Filter for VFD Systems Modern factories use more variable frequency drive equipment than before. A variable frequency drive helps control motor speed, reduce energy waste, and improve process control. But when many VFD systems operate in the same electrical network, VFD harmonics can become a serious power quality problem. VFD harmonics create harmonic distortion in the current wav...
SVG for Industrial Motor Loads Motor loads are common in factories, mines, water treatment plants, commercial buildings, and pumping systems. These loads are reliable and useful, but they also create reactive power demand. When reactive power is not controlled, the system may face poor power factor, higher current, voltage instability, and extra stress on electrical equipment. This is why S...
