Abstract ：
With electric vehicles' popularity, a surge has been created in demand for charging infrastructure. As a result, the maintenance of charging piles has become a critical issue that requires attention. To effectively utilize the fault features of the front and back circuits in case of the charging pile fails, a multifeature fusion model is proposed in this article. First, use the front- and back-stage feature information fusion module to fuse the collected front-stage fault feature quantity signals and the back-stage fault feature quantity signals. Then, the spatial and temporal feature extraction modules are used to mine the spatial and temporal high-dimensional features in parallel. Finally, through the spatiotemporal feature fusion classification module, the spatial and temporal features are fused and classified to achieve the purpose of fault diagnosis. The proposed method employs deep learning techniques, which avoids the cumbersome steps involved in graphical input and the errors arising from manually selecting features in traditional deep learning algorithms and gives full play to the parallel diagnostic performance of deep learning. The simulation results demonstrate that the proposed method outperforms other comparative algorithms in terms of diagnostic accuracy, convergence speed, and overfitting suppression, and has excellent noise immunity, which can cope with the noisy situation of charging piles. In the experimental test, the fault diagnosis accuracy of this method reached 96.36%, and its recognition sensitivity for most fault categories was higher than that of the comparison model, which further verified the superiority and robustness of this method.

This paper proposes a novel Y-Sepic high boost DC-DC converter, which is characterized by high voltage gain, continuous input current, low voltage stress of the switch and diodes, and high efficiency. The proposed converter is obtained by hybridizing the Y-source and Sepic converters. With the coupled inductor turns ratio introduced in the converter, the circuit can operate in an appropriate duty cycle D while maintaining high voltage gain. The working states of the proposed converter are discussed. Then, the voltage and current stresses of components are deduced. The device design considerations have been presented. The power losses and efficiency are calculated. The derivation of the real voltage gain and the voltage gain in DCM have been performed. Besides, a small signal analysis and comparisons with other topologies have been conducted. Finally, a prototype made in the laboratory verifies the effectiveness of the proposed converter.

Abstract ：
A high-boost interleaved DC-DC converter that utilizes coupled inductors and voltage multiplier cells (VMC) is proposed in this paper. The input power supply connects to switches through the primary sides of two coupling inductors with an interleaved structure, which reduces the voltage stresses of the switches and lowers the input current ripple. Two capacitors and a diode are placed in series on the secondary side of the coupled inductors to enhance the high boost capability. The implementation of maximum power point tracking (MPPT) is facilitated by the simplification of the control system through common ground. To verify the effectiveness of the proposed converter, an experimental platform and a prototype based on a turns ratio of 1 are presented. The test results show that the voltage stresses on the switches are only 1/8 of the output voltage. The operating principle and design guidelines of the proposed converter are described in detail. The experimental results show that the converter is efficient and stable over a wide power range.

Abstract ：
Although deep convolutional neural network (CNN) has been widely used in the breast cancer detection based on thermal imaging technology, this scenario still did not receive enough attention in the mobile devices with limited resource. In addition, there still exists challenge on how to assist front view thermal imaging by side one during breast cancer detection. This study proposes a multi-input lightweight CNN named Multi-light Net in order to achieve more accurate early detection for breast cancer, which combines the thermal image from multiple perspectives with the lightweight CNN on the basis of model performance and scale. In addition, a new weighted label smoothing regularization (WLSR) is proposed for the Multi-light Net with the purpose of increasing the network's generalization ability and classification accuracy. The experimental results demonstrate that the proposed approach by combining front view with side view can achieve more significant results than the common one using only front view during breast cancer detection, and the proposed Multi-light Net also exhibits an excellent performance with respect to the currently popular lightweight CNN. Furthermore, the proposed WLSR loss function can also lead to both faster convergence rate and more stable training process during network training and ultimately higher diagnostic accuracy for breast cancer.

Abstract ：
Effective analysis and classification of operational events in distribution networks (DNs), particularly those involving photovoltaic (PV) systems and electric vehicle charging stations (EVCSs), are essential for mitigating potential disturbances. This paper introduces a robust ensemble framework designed for power quality disturbance (PQD) analysis and event classification within DNs. The methodology begins with an enhanced empirical wavelet transform (EEWT), which incorporates spectral trends and window functions to accurately decompose PQDs caused by various events. These decomposed signals are then analyzed for amplitude and frequency characteristics using a mean sliding window-improved Hilbert transform (IHT). Based on these decompositions and inherent periodic features, a scale and cycle-based feature set, including time-dependent spectral features (TDSF), is formulated to differentiate between events. This feature set is subsequently classified using a light gradient boosting machine (LightGBM) to ensure precise event identification. The proposed approach is validated on a modified IEEE 13-node DN integrated with PV systems and EVCSs, simulating scenarios such as synchronization, outages and islanding. Under various noise conditions, the average accuracy of event identification reaches 99.33%, significantly outperforming other benchmark methods. Furthermore, the method's effectiveness is verified through real-time hardware-in-the-loop simulation, achieving an event identification accuracy of 98.33%. The results demonstrate that the proposed framework exhibits enhanced robustness and lower computational complexity compared to existing state-of-the-art methods.

Abstract ：
Magnetic nanoparticles (MNPs) used for magnetic hyperthermia can not only damage tumor cells after elevating to a specific temperature but also provide the temperature required for thermosensitive liposomes (TSL) to release doxorubicin (DOX). MNPs injected into tumor will generate heat under an alternating magnetic field, so the MNPs distribution can determine temperature distribution and further affect the DOX concentration used for tumor therapy. This study proposes an asynchronous injection strategy for this combination therapy in order to improve the DOX concentration value for drug therapy, in which the MNPs are injected into tumor after a certain lagging of TSL injection in order to increase the TSL concentration inside tumor. In addition, the evaluation of treatment effect for this combination therapy is implemented by considering two different MNPs concentration distributions and two biological heat transfer models. The simulation results demonstrate that the treatment effect for combination therapy can be significantly improved after considering the proposed asynchronous injection strategy, which can mainly attribute to the improvement of DOX concentration. The DOX concentration difference during therapy is generally relevant to both the lagging time of different injections and the local temperature distribution due to MNPs concentration distribution.

Abstract ：
To support higher voltage onboard power supply system and electric vehicle (EV) endurance scheme, reconfiguration on novel unbalance levels strategy is developed and adopted in a three-level bidirectional inductor-inductor-capacitor (LLC) resonant converter for wider voltage charging between supercapacitor energy storage (SCES) and battery energy storage (BES) in hybrid energy storage system (HESS), which the proposed converter is composed of an LLC resonant tank module (RTM) and two three-level coupling cascaded neutral point clamping active bridge (3L-CCNPC). Also, the definition of each voltage gain mode in forward and backward workings is established by hybrid modulation strategy with flexible multilevel output ability of novel active bridge. Besides, a wider range of the unified bidirectional voltage gain is achieved by switching among multiple voltage gain modes, which can be implemented by moving among unified bidirectional voltage gain points. Based on the optimization objectives, such as narrowing the pulse frequency modulation (PFM) variation range, the parameters of LLC RTM are designed. Finally, the results from built experimental prototype can verify that the obtained voltage gains are all close to the theoretical design values, and the key waveforms visually reflect the characteristics of novel unbalance levels strategy adopted in bidirectional voltage gain modes of each gain point.
