AC/DC converters used in HVDC transmission systems inject harmonics into their associated ac and dc systems. Such converters are also proposed in conjunction with wind power generation, fuel cells and some other energy storage devices. Series-tuned passive filters are used to prevent the harmonic currents from entering into the ac network. However, the passive filters get detuned if the system frequency changes or if the filter parameters change due to temperature variation or age. In this paper, a new concept of active filters is presented, which do not have the limitations mentioned above. Basic concepts and design of active filters for eliminating ac harmonics are considered and preliminary computer simulation results are presented.
