The harmonic currents affect the installed serialequipment identical to reactive currents. Consequently,harmonic current distortion can result in overheating ofthe supply transformer, cables and so on. Depending onthe impedance of the power grid, harmonic currentdistortion can lead to voltage distortion also affectingother equipment powered by the same transformer.Voltage distortion is increasing losses, causes prematureaging and worst of all erratic operation. The built-in DCcoil reduces most harmonics, but if more reduction isneeded, Danfoss offers two types of passive filters.The Danfoss AHF 005 and AHF 010 are advanced harmonicfilters, not to be compared with traditional harmonic trapfilters. The Danfoss harmonic filters have been speciallydesigned to match the Danfoss frequency converters.AHF 010 is reducing the harmonic currents to less than10% and the AHF 005 is reducing harmonic currents toless than 5% at 2% background distortion and 2%imbalance.3.6.14 Output FiltersThe high-speed switching of the frequency converterproduces some secondary effects, which influence themotor and the enclosed environment. Two different filtertypes, the dU/dt and the Sine-wave filters, are in place toaddress these side effects.Selection VLT® AQUA Drive FC 202 Design GuideMG20Z102 - VLT® is a registered Danfoss trademark 633 3
