Abstract ：
This article puts forward a brand-new high-boost DC-DC converter. The converter adopts a Boost structure on the input side, inheriting the advantages of continuous input current, making it besuitable for renewable energy applications. The rear stage of the converter integrates the three-winding coupled inductor and the voltage double unit. As a result, a high voltage gain can be achieved by using a coupled inductor with a relatively small total turn ratio, and the degree of freedom in adjusting the voltage gain is also improved. The low switch voltage stress allows the use of low voltage rating devices. Additionally, the clamping circuit reutilizes the energy stored in the leakage inductance of the coupled inductor, thereby enhancing the efficiency. The article discusses the operating modes of the converter in detail and compares its performance with other converters. Finally, an experimental prototype is built for verification, and the experimental results match the theoretical analysis. © 2025 Science Press. All rights reserved.

Abstract ：
To reduce the computation and complexity of traditional multi-vector model predictive current control (MPCC) algorithm and ensure good control performance, a novel multi-vector MPCC algorithm was proposed to quickly screen the second voltage vector. According to the principle of current non-differential beat control, the d and q-axis current decision factors were defined by the d and q-axis current difference, which simplifies the selection process of the second voltage vector, reduces the calculation of the control chip, and maintains the advantage of low current ripple. On the basis of the new two-vector MPCC algorithm, a novel three-vector MPCC algorithm combining the d and q-axis current decision factors and the effective voltage vector table to directly select the second voltage vector was proposed. Experimental results were presented showing that the new multi-vector MPCC algorithm maintains the control performance of the traditional multi-vector MPCC algorithm while the computation of the new two-vector MPCC algorithm is reduced by 33. 96% and the computation of the new three-vector MPCC algorithm is reduced by 48. 7% . © 2024 Editorial Department of Electric Machines and Control.

Abstract ：
To enhance the accuracy of theft detection for electricity consumers, this paper introduces a novel strategy based on the fusion of the dual-time feature and deep learning methods. Initially, considering electricity-consumption features at dual temporal scales, the paper employs temporal convolutional networks (TCN) with a long short-term memory (LSTM) multi-level feature extraction module (LSTM-TCN) and deep convolutional neural network (DCNN) to parallelly extract features at these scales. Subsequently, the extracted features are coupled and input into a fully connected (FC) layer for classification, enabling the precise detection of theft users. To validate the method's effectiveness, real electricity-consumption data from the State Grid Corporation of China (SGCC) is used for testing. The experimental results demonstrate that the proposed method achieves a remarkable detection accuracy of up to 94.7% during testing, showcasing excellent performance across various evaluation metrics. Specifically, it attained values of 0.932, 0.964, 0.948, and 0.986 for precision, recall, F1 score, and AUC, respectively. Additionally, the paper conducts a comparative analysis with mainstream theft identification approaches. In the comparison of training processes, the proposed method exhibits significant advantages in terms of identification accuracy and fitting degree. Moreover, with adjustments to the training set proportions, the proposed method shows minimal impact, indicating robustness.

Abstract ：
In this article, a novel three-winding coupled inductor (TWCL) based high-gain dc-dc converter is proposed, which combines a TWCL technique and a voltage multiplier cell, avoiding large duty cycle and resulting in a high gain of the converter. The input current continuity and common ground make the proposed converter suitable for renewable energy. In addition, the converter also has the characteristics of low voltage stress on switch and high efficiency. A passive clamp circuit recycles the energy stored in the leakage inductor of the coupled inductor and reduces the voltage spike of the switch, thus improving efficiency. The steady-state analysis, parameter design, and loss analysis of the proposed converter are discussed in detail, and the comparison among existing high-gain converters is discussed as well. Finally, experimental results verify the theoretical analysis.

Abstract ：
直流线路故障保护是基于模块化多电平的柔性直流输电(MMC-HVDC)系统必须解决的关键问题。首先分析了基于混合旁路直流故障隔离的原理与隔离步骤,通过旁路桥臂转移故障电流,在零电流下断开快速机械开关,实现换流器与直流线路的物理隔离并清除直流故障电流。系统重合闸无需解锁子模块,通过旁路桥臂判断故障是否消除,并在零电压下闭合快速机械开关恢复系统运行。当判断直流故障为永久性故障时,换流器能够重启作为STATCOM运行。混合旁路直流故障保护方案能有效应对永久性、瞬时性直流双极短路故障。最后通过在PSCAD/EMTDC建立双端柔性直流输电仿真模型验证该方案的可行性。
