Design of passive filter based on fundamental magnetic flux compensation
Abstract：In order to improve the performance of traditional passive filter,a new passive filter is designed according to the principle of the fundamental magnetic flux compensation,which is mainly composed by the transformers,passive filters and a passive resonant circuit.The basic principle is that the transformer primary side is in series between the power supply and harmonious wave source,and then the secondary side is connected with the power network through the fundamental resonant circuit.That can make fundamental a low resistance and high resistance to harmonics,and so harmonics are suppressed.In order to further improve the filtering effect a universal passive filter is added.The simulation results show that the designed filter has good filtering properties and can effectively inhibit the harmonics of the grid side.
