Consumer electronics, Data Centers, HVAC systems and a large range of industrial applications, namely power electronics based, can cause high disturbances into the supplied electricity. The disturbances comprise of harmonic current generated by such loads, and the voltage distortion created by the harmonic currents. The main problem with the harmonic currents is that, they can cause overheating in the local supply distribution transformer and in the installation itself. Indian Electric utility companies are starting to be more concerned about harmonics in the transmission and distribution network, and imposing strict harmonic limits on consumers. Active harmonic filter is a potential solution to mitigate harmonics problems. The usage of active harmonic filter is expected to increase drastically in Indian industries, to meet utility requirements. This paper discusses technology variants of Active Harmonic Filter from different aspects, and their advantages and disadvantages.
