Application prospect of a new transformer inductive filtering technology

Different from passive and reactive filtering methods, this paper proposes a new transformer inductive filtering technology. Its characteristics is that it develops the potential electromagnetism capability of the transformer and makes use of the ampere-turn balance action of the interior coupling winding, which can suppress the harmonics in the secondary winding and avoid the harmonics flowing into the primary winding. In addition, it can effectively abate the negative effect of the harmonic magnetic potential on the transformer. This paper introduces three types of new supply transformers, expounds the interrelation and combined technical characteristics, then expands on its research progress and the industrialization condition. Furthermore, the paper summarizes the practical significance of new inductive filtering technology and its application prospect. The author adopts systematic analysis method, and carries out systematic research for the transformer inductive filtering technology. By means of various model experiments analysis, it verifies the good filtering influence that the new inductive filtering technology has.
