Active filters are actively used devices helping to improve the quality of the electric power generated from alternate energy sources. These devices achieve the reduction of harmonic content and the reactive power helping the energy systems to be efficient and reliable. At Sinotech Group, we are in the business of designing advanced active filters called active filters in renewable energy field. Our results are consistent with the mainstream specified standards and therefore assist in smooth integration of the alternative energy solutions and thus act as useful parts of the contemporary energy systems everywhere on the globe.
