“…Input AC line reactor, k-transformer, passive harmonic filter, multi-pulse drive arrangement (12,18, 24-pulse), active harmonic filter (AHF), and a Hybrid harmonic filter are some of the approaches available to mitigate the impacts of harmonics in a system (17). Among these various available techniques, the use of an AC line reactor has become popular in VFD driven applications due to its lower cost in comparison to other techniques as mentioned above (17)(18). This amount of harmonics reduction is not sufficient and needs improvements so as to meet the defined regulations and standards for VFD use in a system.…”

With the goals of a better power factor and reduction in energy use, variable frequency drives (VFDs) have been standardized in various industrial applications including Heating, Ventilation, and Air-conditioning (HVAC) systems. However, key issues related to the deterioration in the power quality associated parameters (voltage harmonic distortion and current harmonic distortion) due to the growing number of VFDs demand a wholesome analysis of the problems faced by the users. In this present work, an analysis has been performed to investigate the potential impact of using alternating current (AC) line reactor and direct current (DC) link choke combination on harmonic mitigation in a VFD driven water-cooled centrifugal chiller compressor. Using a combination of AC line reactor and DC link choke as one of the low cost solutions in harmonic mitigation of a VFD driven load in HVAC systems can be decided based on the investigation done in this research work.
