Abstract :
An integrated structure formed by an annular “inductor-capacitor” is proposed firstly in this paper. Based on general arc transmission theory, the distributed-parameter model of the LC unit is established. Besides, the turn-to-turn electromagnetic parameter is extracted using finite element method. In order to verify the proposed design theory, several EMI filters formed by LC units are designed according to the specifications.
