Abstract ：
在电磁干扰(EMI)滤波器的设计和功率变换器的EMI噪声预测中,共模扼流圈的精确建模至关重要.然而,在高频下受共模扼流圈寄生参数的影响,现有模型难以准确表征其滤波特性.该文分析现有模型的缺点在于无法完整反映共模扼流圈的内部电场特性,因此根据共模扼流圈差模分量在高频下的插入损耗谐振点特性提出一种新的高频模型,该模型通过综合考虑端部和绕组中间寄生电容的影响从而完整表征差模分量的电场特性,并解析新模型电路结构给出模型中寄生参数的提取流程.实验结果表明,新模型在 150 kHz～30 MHz下具有良好的拟合精度,证明了该模型的准确性.

Abstract ：
Common mode chokes (CMCs) are key components in electromagnetic interference (EMI) filters, and accurate modeling of these components is critical for filter design and EMI noise simulation. This article proposes a behavioral model and parameter extraction technique for characterizing three-phase four-wire common mode chokes (4W-CMCs). The proposed model considers the inductance nonlinearity caused by the nonlinear permeability of manganese-zinc ferrite and nanocrystalline magnetic materials, as well as the asymmetry and local symmetry in the winding distribution of 4W-CMCs. The parameters for the common mode and differential mode (DM) models are extracted using a parameter extraction program and a simple equation-based method, respectively. For the DM model parameter extraction, this article proposes a measurement method that utilizes the local symmetry of 4W-CMCs. The equivalent circuit of this measurement method decouples the interwinding capacitance (C-W) from the DM inductance parallel capacitance (C-D) by transforming two-port network parameters, greatly simplifying the parameter extraction process. The accuracy of the model and the effectiveness of the method are validated through experiments using several 4W-CMCs with manganese-zinc ferrite and nanocrystalline magnetic cores.

Abstract ：
High-power inductors are fundamental components in high-power DC-DC converters, with their performance being a crucial metric of converter efficiency. This paper presents an in-depth analysis of a novel calculation method for the air gap length in such inductors. Taking into account the effects of air gap diffusion and the winding magnetic field, an expression for the air gap diffusion radius is derived, focusing on a distributed air gap structure. Furthermore, models for calculating the air gap and winding reluctance are developed, grounded in electromagnetic field theory. An equivalent magnetic circuit model, formulated based on Kirchhoff's second law, facilitates the proposed method for air gap length calculation. This study also involves the development of 3D models for both discrete and decoupled integrated inductors. The comparison between simulation outcomes and calculated air gap lengths indicates a maximum error of less than 8%, with the minimum error being as low as - 0.79%. Compared with traditional methods, the calculation method proposed in this paper has significant advantages. Additionally, the discrepancy between calculated values and experimental measurements is found to be 1.11%. These results validate the accuracy and applicability of the theoretical analysis and calculation method, underscoring their significance in the design and optimization of high-power DC-DC converters.

Abstract ：
Pad misalignment is almost inevitable in most wireless power transfer (WPT) systems, which leads to system performance degradation due to the variation of system parameters. Based on S-S and P-S compensation topology, this paper proposes a compact WPT system with dual-coupled SP-S compensation with anti-offset characteristics. Two coaxially arranged, mutually decoupled, rounded square coils are used as the energy transmitting coils, which are coupled with a single square receiving coil to improve the anti-offset tolerance in the X and Y directions. In the process of receiving coil offset, the output of one transmitting coil loop is increased and the output of the other coil loop is reduced by resonance parameter configuration, so that the system output fluctuates gently with the offset of the receiving coil. The design method of the structural parameters of the square decoupling coil is put forward and the influence of shunt compensation capacitance on the offset resistance of output is also analyzed. An experimental platform is built to verify the feasibility of the proposed method and the anti-misalignment performance of the proposed WPT system. ©2024 Chin.Soc.for Elec.Eng.

Abstract ：
The ignition module is the start-up of the pulsed plasma thrusters (PPT), in which the high-voltage pulse transformer is the most important component, as its output characteristics can affect the reliability of PPT ignition. This article discusses the influence of the parasitic parameters of the high-voltage pulse transformer on the output pulse waveform. It reveals that the leakage inductance of the high-voltage pulse transformer is the root factor affecting the output voltage's rise time, while parasitic capacitance and excitation inductance have little influence and can be ignored in most real applications. The smaller the leakage inductance of the high-voltage pulse transformer, the better the overall performance of the output pulse voltage waveform. The toroidal high-voltage pulse transformer's leakage inductance mechanism is analyzed based on the electromagnetic field principle, and the theoretical calculation model of leakage inductance is established. Furthermore, the high-voltage pulse transformer optimization guideline is proposed. The optimized high-voltage pulse transformer can reduce leakage inductance by 71.8%. Finally, the experimental results verify the theoretical analysis to be correct and useful.

Abstract ：
Capacitive power transfer (CPT) technique uses coupled metal plates for energy transmission, which has the advantages of negligible eddy-current loss and low weight. To achieve efficient power transfer, the CPT system often adopts circuit resonance and impedance compensation, which are generally realized by integer-order components, such as inductors and capacitors. However, it remains a fundamental challenge to create a CPT system whose transfer efficiency and output power are robust against the variation of resonant frequency and the coupled plates' relative position. Therefore, this article proposes a robust fractional-order autonomous CPT system containing a fractional-order inductor. Theoretical analysis shows that the transfer efficiency and output power of the proposed fractional-order CPT system are inherently robust not only to the variation of the coupled plates' relative position but also to the resonant frequency. In contrast, the transfer efficiency and output power of traditional integer-order CPT systems are sensitive to the resonant frequency. The available experimental results verify the effectiveness of the proposed system.

Abstract ：
The complex permeability of magnetic materials at radio frequencies significantly impacts the electromagnetic compatibility (EMC) characteristics of magnetic components. The precision of its measurement is crucial for the design, selection, and study of EMC properties of magnetic components. This article discusses the key material parameters affecting the radio frequency characteristics of magnetic materials and provides a detailed analysis of how these parameters influence the complex permeability of magnetic materials. It reveals why traditional methods for measuring the complex permeability of magnetic materials are not applicable at high frequencies. This article identifies the parasitic inductance and capacitance in the measurement winding as the primary factors affecting measurement accuracy. Consequently, it proposes a new method for testing the complex permeability of magnetic materials in the radio frequency range, considering the effects of parasitic parameters in the measurement winding. This method effectively combines small-signal measurements with finite element simulation to calibrate parasitic parameters, significantly extending the frequency range of the measurement results. Experimental findings demonstrate that the proposed method accurately extracts the characteristic parameters of magnetic materials in the frequency range from 30 MHz to 1 GHz.

Abstract ：
Wireless power transfer is widely used due to its safety and convenience. The rectification circuit is an important part of the WPT system. Different rectification circuits and input parameters may lead to different responses and output gains in the actual applications. Usually, the fundamental harmonic analysis method is adopted to analyze the WPT system's performance. However, this method cannot present the differences between different parameter applications. It is because only the fundamental harmonic is taken into consideration. In this paper, the influence of harmonics is studied. Moreover, the equivalent impedance model of the rectification circuits is built. It can take the input and rectification circuit parameters into consideration, which is quite different from the traditional method. Based on the equivalent impedance model of the rectification circuits, the response model of the WPT system can be analyzed. Finally, a WPT system is used for the validation. The key waveforms calculation results are almost the same as the measured results. It verifies the proposed method to be correct and useful. It provides a good basis for WPT system optimization. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract ：
With high power density and high-frequency power electronics technologies, parasitic capacitances of inductors and transformers have been widely discussed, in which parasitic capacitance may lead to electromagnetic interference (EMI) and efficiency performance degradation. Therefore, it is significant to analyze and model the parasitic capacitance of the inductors and transformers. This paper proposes a new parasitic capacitance calculated model of multilayer windings inductors and transformers. Based on the electromagnetic field theory, it can fully consider the edge effect of multilayer inductor windings, including the edge effect between adjacent and non-adjacent layers. Finally, the accuracy of the model is validated by simulation and experiment. Compared with the traditional parasitic capacitance calculated method, the proposed model can calculate the parasitic capacitance more accurately, and the maximum error between calculations and simulations is less than 8%.
