Application of inductive filtering technology in industrial rectifier power system

Application of inductive filtering technology in industrial rectifier power system is studied in this paper. Firstly, the single phase equivalent circuit of inductive filtering and its basic principle is introduced; then, the power circuit topological of primary equipment is proposed, which is designed for an industrial rectifier power system; finally, a detailed field-test is taken, and the test results indicate that the industrial rectifier power system that adopted inductive filtering technology not only can effectively suppress the harmonic of industrial custom power system, but also decreases the magnetic flux of rectifier transformer. Consequently, the additional harmonic loss of rectifier transformer is reduced significant which lead to the energy consumption reduction in system range.
