In the last few years, the increasingly presence of electronic equipment in homes and commercial enterprises caused the consumer demand for better quality energy has been growing and solidifying between the different user profiles. This fact has transformed the profile of the loads of the electricity consumers; with linear loads before and now predominantly with non-linear loads. These non-linear loads insert harmonic currents frequency on the power grids, causing hence the distortion in the waveform of the current supplied. Such distortion impacts on investments in solutions by the electric utilities and the consumers, in order to decrease the circulation of these components in the electric power grid. This paper aims to develop a design and an analysis under the passive filters tuned to residential systems for reduction of harmonic frequencies, which aims to limit the motion of these currents in the power grid, especially the influence of the harmonic component of 3rd order. For this purpose, the insertion of passive filters (shunt type and block) including specific topologies, which have reduced volume, weight and costs in comparison to most conventional arrangements employed and established in the literature.
