[Abstract]:Switching power supply is widely used in information communication system, industrial control, air traffic and so on. Power density is one of the key indexes of switching power supply. Firstly, from the point of view of increasing the power density of switching power supply, the paper points out that passive component integration is an effective method to realize high power density, and introduces the structure and example of PCB and FMLF integration technology. The materials, advantages and disadvantages of the two integrated technologies are compared and summarized, and the important theoretical value of establishing the distributed parameter model is explained. Secondly, the physical structure and equivalent model of three different FMLF are given, and the integrated structure I of EMI filter and boost inductor using three kinds of FMLF is proposed, and the electromagnetic analysis of the integrated structure I is explained. The distribution parameter model of integrated structure I is established, the influence of different circuit parameters on insertion loss of EMI filter is investigated, and the design process of experimental prototype of 1kW PFC converter is introduced. The experimental results verify the correctness of the theoretical analysis. Then, a new topology based on the classical PFC converter topology is proposed, and an integrated structure 鈪，
