Planar PCB high-frequency transformer is the key component that affects the characteristics of conducted common mode (CM) electromagnetic interference (EMI) of switching power supply. In this paper, the calculation method of the effective capacitance of the CM port of the planar transformer is explained, and the effective capacitance of the CM port of the planar transformer is further determined by the simulation method. Then, the method of CM EMI characteristics evaluation of planar transformer insertion loss (IL) is explained and expounded, and its simulation and measurement methods are introduced. Finally, based on the analysis and research of the defects of the original transformer IL model, the high-frequency model of transformer IL is proposed, and the advantages and effectiveness of the proposed high-frequency model in the conduction frequency band are verified by the actual measurement. © 2023 IEEE.

Abstract ：
Plane transformers are vital components of high-frequency power electronic converters, and the calculation and optimal design of their parallel winding losses pose significant challenges in the design process. This article proposes a theoretical calculation method for winding losses based on impedance matrix and circuit equations, and it derives the significance and acquisition methods of impedance matrix parameters under high-frequency conditions. Building upon the proposed theoretical calculation method for winding losses, the article performs classification analysis of circuit equations to determine the constraints of the optimization problem. It establishes a mathematical model for optimizing winding losses in a single topology and provides a general solution method for designing the optimal structure of winding losses. Finally, experimental measurements are conducted to validate the effectiveness of the optimization method presented in this article. © 2023 IEEE.

Abstract ：
The reverse phase winding is an effective method to suppress the common mode noise of the PFC circuit. However, to obtain the best effect, it is necessary to quantitatively analyze the parameters of the reverse phase winding and draw effective conclusions, especially for the leakage inductance and turn ratio of the reverse phase winding; there is a lack of in-depth understanding and analysis at present. In this paper, the high-frequency equivalent circuit of the reverse phase winding of the power inductor is established, and the mathematical model is calculated. This paper discusses the influence trend of compensation capacitance, primary and secondary side leakage inductance and the number of turns of reverse phase winding on the noise suppression effect, and gives the optimal design method and carries out experiments, which greatly optimizes the common mode noise of PFC circuit, and puts forward an effective theory. © 2022 IEEE.

Abstract ：
As an important role in electromagnetic interference (EMI) solving of switching power supply, the EMI filter's performance and integrated design are of great significance to improve the power density of switching power supply. This paper combines the basic means of magnetic integration and electrical integration of the filter and utilizes the integration advantages of flexible multilayer foils (FMLFs) to integrate the common and differential mode inductor and Y capacitor of the filter into a unit module. At the same time, the design value of the differential mode inductor is increased through the decoupling design of the common and differential mode inductor. Compared with the traditional discrete filter, the integrated filter omits the Y capacitance and reduces the X capacitance, which can effectively reduce the board area of the EMI filter on the premise of consistent performance. Combined with the design process of the integrated filter, to improve the integration, this paper mainly discusses the process of core selection, performance prediction, and performance modeling, and finally verifies the feasibility and effectiveness of this scheme through a noise comparison experiment. © 2022 IEEE.
