A review and study of harmonic mitigation techniques
2012 International Conference on Emerging Trends in Electrical Engineering and Energy Management (ICETEEEM), 2012A periodic wave having a frequency that is an integral multiple of the fundamental power line frequency component is harmonics. They are the byproducts of modern electronics devices so it is necessary to mitigate the harmonics and offer techniques to mitigation of harmonics.

Harmonic mitigation in AC-AC converter
2014 Students Conference on Engineering and Systems, 2014Non-linear behavior of power semiconductor switch and non-linear load creates power quality problem in an ac to ac converter. These non-linear switches and load injects significant harmonic on Load side as well as on source side. In this paper an attempt has been made to reduce these harmonics using staircase PWM technique and passive filter.

Mitigation of harmonic distortion with passive filters
2016 17th International Conference on Harmonics and Quality of Power (ICHQP), 2016The growing use of nonlinear loads in commercial, residential and industrial sector has been distorting the currents and voltage waves of the power network. These distortions are known as harmonic distortions, and its presence can cause serious problems to equipment linked to polluted sources.

Harmonic mitigation technique for multilevel inverters in power systems
2014 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2014A new procedure to mitigate some harmonics is presented for a 5-level cascaded inverter, varying the modulation index. The two switching angles α 1 and α 2 are computed by using a procedure based on graphycal analysis by using Chebyshev polynomials and the Waring's formulae. The proposed mitigation technique is applied to reduce a pair of harmonics

A deterministic harmonics mitigation technique for five-level inverters
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014A deterministic algorithm aiming at reduction of harmonic content in three phase, five-level cascaded inverters is proposed. The procedure starts from a non-linear system consisting of disequations and, using Chebyshev polynomials and Waring's formula, for any assigned modulation index computes those switching angles α 1 and α 2 reducing harmonics ...

Analysis of harmonic mitigations using hybrid passive filters
2014 16th International Power Electronics and Motion Control Conference and Exposition, 2014With the recent development in the power electronic devices, the use of power electronics in controlled Variable Speed Drives (VSD) is increasing in industrial and domestic applications. These controlled VSDs provide many advantages and flexibility in those applications, but at same time cause harmonic distortion in the power system.

Using broadband passive harmonic filters for harmonic mitigation in AC drives
2014 16th International Conference on Harmonics and Quality of Power (ICHQP), 2014Various technical solutions are used to reduce harmonics generated by variable speed drives (VSD). AC VSD belong to their very significant sources with negative influences on the quality of electrical energy at the point of their connection to the network.

Harmonic Mitigation and a Practical Study of Torque Harmonics in Induction Motor Startup
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018In this paper, the nature of harmonics due to the operation of nonlinear power system components, the effects of harmonics and methods to eliminate the harmonics will be discussed briefly. Harmonics caused by power electronic devices and their impact on other loads in an industrial facility are a primary concern in this paper.

A Mitigation Technique for Harmonic Downconversion in Wideband Spectrum Sensors
IEEE Transactions on Instrumentation and Measurement, 2015The down conversion of radio frequency components around the harmonics of the local oscillator (LO), and its impact on the accuracy of white space detection using integrated spectrum sensors, is studied. We propose an algorithm to mitigate the impact of harmonic downconversion by utilizing multiple parallel downconverters in the system architecture ...
