“…The research related to power electronic devices (PEDs) is mainly aimed at creating new circuit solutions or improving existing ones, as well as at improving the efficiency of PEDs, improving the switching of power elements, etc. [1][2][3][4][5][6][7][8][9][10][11]. In the last few years, the research related to renewable energy sources, electric vehicles, and energy storage cells has also been increasing due to their rapid integration into people's daily lives.…”

This work demonstrates the feasibility of using Kali Linux in the process of power electronic device research. The novelty in this work is the use of Kali Linux in the process of power electronic device research. This operating system is mainly used for the penetration testing of various communication devices but not for power electronic device research. The aim of this work is to study the level of network security (the type of security vulnerabilities that a power electronic device has) and whether the data exchange between the power electronic device and the monitoring and control center is secure. Additionally, penetration testing has been carried out. Kali Linux was used to implement these tasks. Penetration testing was performed to verify how the studied power electronic device reacted to various TCP DoS attacks—could it be accessed, was it blocked, etc. Kali Linux and some of the tools built into the operating system—Nmap, hping3, Wireshark, Burp Suite Community Edition—were used for this study. During the penetration tests, a characterization of the traffic being processed/generated by the studied power electronic device was carried out to evaluate and analyze what impact each TCP DoS attack had on the device’s performance. In order to conduct the study, an experimental setup was designed. This experimental network was not connected to other networks, so the cyber attacks were controlled and confined within the experimental network. The research carried out validated the use of Kali Linux for the study of power electronic devices. From the obtained results, it is found that the studied power electronic device provides a certain level of network security, but the data exchange is insecure.

In this paper, a novel non‐isolated bidirectional dc‐dc converter (NBDC) is proposed. Compared with other topologies proposed recently, the proposed converter has the advantages of high voltage gain, wide voltage range, and common ground, which is suitable for the application of electric vehicles (EVs). The operating principle, steady‐state analysis, performance comparison, and the small signal modeling of the proposed converter are presented in detail. Finally, a 265‐W prototype is built to verify the feasibility of the proposed converter. The experimental results well confirm the corresponding theoretical analysis, and the prototype has a peak efficiency of 92.81% and 93.61% in step‐up mode and step‐down mode, respectively.

This paper introduces a novel topology for a non‐isolated bidirectional multiphase single inductor (BMPSIC) DC–DC converter. The proposed BMPSIC requires only a single inductor, irrespective of the number of arms, and features reduced volume and weight compared to the total magnetics needed for a conventional converter with similar ratings. The proposed BMPSIC advantages include a high DC voltage gain without operating on a large duty cycle, voltage stress on the power switches equal to that at the high‐voltage port, easy implementation, and a lower cost for application at high‐power densities. Furthermore, this topology requires only one current and voltage control loop. This paper thoroughly details the steady‐state operating principles of the inductor current continuous mode. It provides theoretical and mathematical analysis, including a comparative analysis of the proposed BMPSIC against earlier DC–DC converters, highlighting the superior performance and efficiency of the BMPSIC. An 8‐kW laboratory prototype, designed as a proof of concept, has been meticulously developed and tested, showcasing the performance of the converter across a broad range of load variations. The efficiency measured for the rated load exceeded 98.2% at the low‐voltage port of 250 V and the high‐voltage port of 400 V. Additionally, the article features Video S1, which illustrates the functioning of the converter.
