Abstract ：
光伏发电占我国发电总量的比重越来越大。飞跨电容多电平拓扑能够有效减小电感体积，因此在高功率密度、高效的场合具有应用前景。但飞跨电容逆变器实际运行中，会出现飞跨电容电压不均压的情况，不仅会使电路失去倍频效应，还会使开关管两端的电压应力不均衡，造成损坏。选择七电平FCML作为实验对象，将基于PI控制的均压环拓宽至七电平FCML中，搭建了一台3kW的样机验证了基于PI控制的均压环均压效果的有效性。

Abstract ：
With the rapid development of the new energy industry，the application demand of a wide range of conditions is more and more extensive. As the classical topology of bidirectional DC-DC converter，dual active bridge DC-DC converter has the problems of decreasing soft switching range，increasing current peak value and current RMS value in wide range applications. Therefore，this paper focuses on analyzing the influence of wide input conditions on the characteristics of dual active bridge DC-DC converter under triple phase shift control，and deduces the theoretical expressions of the variation of soft switching range，current peak value and current RMS with switching frequency under wide input voltage. On this basis，a phase-shifting variable frequency hybrid control strategy is proposed. By adjusting the switching frequency，the soft switching range of the dual active bridge DC-DC converter is extended，and the current peak value and current effective value are reduced，and the overall efficiency of the converter is improved. Finally，a prototype of a 1 kW dual-active bridge DC-DC converter based on SiC device is built to verify the effectiveness of the proposed control strategy. © 2024 Science Press. All rights reserved.

Abstract ：
Increasing switching frequency can greatly improve power density of dc-dc power converter, while meets challenges of significant high-frequency dc output ripple. The capacitor filter is a most cost-effective suppression for the output ripple. However, the capacitor parasitic parameters will deteriorate the suppression. The frequency characteristic of the capacitor filter was analyzed by considering the parasitic parameters. Then, a novel parallel dual capacitors filer is proposed, which creates the reverse coupling between the two adjacent capacitors of the filter by constructing opposite current flowing through the capacitors. Using the novel dual capacitors filer as a cell, a novel compact multicapacitors filer of V-shape is further extended. The insert gain test and the prototype with 20 MHz of switching frequency are constructed, and the experiments verified that the novel filters suppress the ripple by maximum about 50% comparing with the traditional capacitor without adding volume and cost.

Abstract ：
The resonant power converters at tens of MHz operate most efficiently at fixed frequency and fixed duty cycle. However, the increase of distributed parameters and parasitic parameters will lead to circuit detuning at high frequency, resulting in the deviation of the system from the optimal working point. In this paper, an iterative commentsoptimization analysis method on parameter sensitivity is proposed. It combines the rectifier and matching network, and obtains the input voltage of rectifier that meets the working requirements of matching network and rectifier simultaneously by numerical iteration to ensure the resonant matching state of the converter. A prototype with 20 MHz, 18 V input and 10 V / 10 W output is built. The prototype works well and the efficiency is 81.4% at full load. The experimental results verify the effectiveness of the proposed parameter sensitivity analysis theory and the feasibility of its guiding experimental debugging. © 2024 IEEE.

Abstract ：
For electric vehicles (EVs) equipped with an onboard charger (OBC) and a wireless power transfer (WPT) system, there will be two charging systems in the EVs, which increases the cost, weight, and complexity. Based on the proposed design of magnetic couplers, this letter proposes a novel integration method for OBC and WPT systems of EV charging. The isolation transformer of the OBC system can be regarded as two strongly coupled coils. The secondary-side coil, namely the receiving coil, can also be loosely coupled with the transmitting coil of the WPT system. Thus, the receiving coil, the compensation, and the rectifier of both the OBC and WPT systems can be shared. In this way, the EV charging system can be capable of conductive charging and wireless charging while still having the advantages of cost effectiveness and high power density. An experimental prototype is implemented to validate the proposal.

Abstract ：
为了解决分布式新能源渗透率提高带来电网的系统等效阻尼和惯性降低的问题,一些学者提出了虚拟同步发电机(virtual synchronous generator,VSG)控制策略.为了能够抑制电网电压不对称跌落时电网电流中的负序分量,VSG 多采用基于两相旋转坐标系下d-q 轴的正负序复合控制;但是正负序分离的延时恶化了故障发生和恢复时VSG 输出电流的过渡过程,造成VSG 过流风险增加.针对此问题,文中首先分析了电网电压对称和不对称跌落故障时电网电压等效幅值波形的特点,并据此提出了一种自动识别出故障类型,实现自适应正负序复合控制的VSG 低电压穿越策略,不仅能抑制不对称故障时输出电流中的负序分量,还减小了正负序分离的延时影响和VSG 出现暂态过流的可能性,使故障发生和恢复时VSG 输出电流的过渡过程更加平滑.最后通过搭建仿真系统验证了文中所提方法的可行性.

Abstract ：
为了使电磁干扰(EMI)滤波器设计达到预期的插入损耗(IL),实现良好噪声抑制效果,需要考虑噪声源阻抗的影响.电压插入损耗法仅能获得噪声源阻抗幅值的范围,且无法求解相位.针对上述问题,在不增加实验设备的前提下,提出基于插入无源二端口网络的噪声源阻抗提取方法.该方法通过在被测设备(EUT)与线性阻抗稳定网络(LISN)之间插入3个不同的无源二端口网络,建立关于噪声源阻抗实部和虚部的二元二次方程组,再结合EMI测试频段范围内实验测量的有效频点噪声电流,以实现噪声源阻抗幅值和相位的精确计算.以一台工业照明LED驱动电源为测试对象,对该方法的有效性和适用性进行了验证.实验结果表明,相较于电压插入损耗法,所提方法能够准确地提取全频段(9kHz～30MHz)噪声源阻抗幅值的精确值,并且能够得到噪声源阻抗相位,从而可以预测EMI噪声电流,为设计性能优良的EMI滤波器提供精确理论基础.
