Five-level MLI-based PV systems have become a crucial option as the relevance of renewable energy keeps increasing because of their increased efficiency, less harmonic distortion, and greater power quality. The study looks at several different control strategies, including grid synchronization approaches and Maximum Power Point Tracking (MPPT), to improve PV system performance and grid interaction. Several modulation techniques are also examined, with a focus on how they might lower harmonics and boost system performance. Examples of these techniques include pulse width modulation (PWM) and selective harmonic elimination (SHE). Further analysis of the structural features of five-level MLI-based systems is done, which helps to clarify the trade-offs between complexity, dependability, and cost. This analysis includes component needs and scalability concerns. Researchers and engineers working on the design, control, and deployment of sophisticated MLI-based PV systems in grid-connected applications may learn from this paper.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"78-108"},"PeriodicalIF":5.0,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10791915","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142890312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, extending the converter operation in the overmodulation zone (OMZ) remains a problem. A key limitation of existing control methods in the OMZ is using the duty cycles calculated for the LMZ without considering the voltage or current reference vectors. This approach can lead to inaccurate calculations and a slower transient response when switching between the two operational zones. To overcome this challenge, a novel reference vector calculation method is proposed in this paper. The proposed approach simplifies the duty cycle calculation and ensures optimal performance in the OMZ by introducing new vector calculations and dividing the OMZ into two subzones. This method also minimizes the transition time between LMZ and OMZs to maximize the usable operating range of MCs. Simulation and experimental results validate the proposed method outperforms two other MMPC methods in improving the MC performance, reducing the transition times between operational zones, and maximizing the converter utilization.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"66-77"},"PeriodicalIF":5.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10783040","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is to provide wireless PCI for electric taxis and fleet vehicles which may require WPT5 charging while on shift and WPT3 off shift charging. The design process of the WPT3/5 BPP VA magnetics is presented. Alternative methods of ferrite core layout and coil overlap to reduce form factor and cross-coupling are investigated. A dual active bridge topology using LCC-LCC tuning demonstrates effective dual-sided control, combining conduction angle, active bridge phase shift, and Selective Coil Energization (SCE) to provide system functionality essential to PCI. Active bridge phase shift is utilized to adjust the relative secondary to primary phase past 90° to enable Zero-Volt Switching (ZVS) in the active bridges when operating at either power class. Experiments demonstrate the proposed WPT3/5 BPP VA charging from an above ground WPT3 UGA, and flush ground mounted WPT5 GA, and show an efficiency increase of 3.6% and 0.7% respectively when the proposed control method is used.

While recent advancements in control and communication have enhanced the functionalities of power electronic converters in applications such as electric vehicles and smart grids, such advancements have also introduced new vulnerabilities, particularly to cyber-physical attacks. The existing literature tends to focus on isolated research areas, and a comprehensive review that encompasses strategies applicable before, during, and after an attack remains lacking. To address this gap, this paper categorizes state-of-the-art research into four key stages of an attack: anticipate and prepare, resist and absorb, detect and evaluate, and recover. Topics reviewed in this paper include converter and cyber-physical attack modeling, converter-based CPS testbeds, system hardening at the cyber and physical layers, attack detection, post-attack evaluation, and recovery strategies. Real-world case studies and practical regulations are also analyzed. Additionally, challenges and opportunities of the resilience framework are discussed. Despite notable advancements in modeling and identifying cyber-physical attacks, considerable efforts are still required to improve attack mitigation strategies and recovery mechanisms.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"28-55"},"PeriodicalIF":5.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10787071","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the enhanced network structure of a meshed DC grid imposes an intricate relation between component and system functionality, complicating the reliability assessment. This paper proposes a stochastic framework for the reliability assessment of DC-SPSs based on a three-stage Monte Carlo (MC) simulation, including component failure sampling, active fault propagation, and reliability index calculation. The proposed method is first validated for a small-sided DC grid through comparison with an analytical method. Later, the model is applied to estimate the reliability, availability, and repair characteristics of a ring-type DC-SPS for a wind turbine installation vessel. The results quantify the impact of redundancy on the system adequacy, show the spread in the subsystem repair times, and reveal the system availability during both the initialization and steady-state operation. Besides the assessment of the designed grid, the MC method is used to perform sensitivity and Pareto analysis, quantifying the impact of component failure rate changes on the SPS reliability, and identifying the contribution of individual components to the system failure characteristic. Combined, these results guide the focus for future SPS reliability enhancements.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1842-1852"},"PeriodicalIF":5.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10770573","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our work has predicted the parameters successfully for the 2.5 kV guard ring design. For training, proximal policy optimization (PPO) and advantage actor-critic (A2C) RL agents were deployed. The network architecture was kept at “auto” with 3 hidden layers of 128 neurons in each layer. Our method is practically feasible and easily implemented as compared to other works, and has been shown in this paper. By using the limited design parameters of the 1.7 kV guard ring device, the trained agent has successfully predicted the design parameters for the 2.5 kV guard ring device, which has been confirmed using TCAD simulations. This work is more accurate, practical, and result-oriented, and we believe that this can significantly minimize the computational cost as compared to the standalone TCAD simulations.

The DC-link capacitance must be selected carefully, to ensure that the voltage ripple remains within defined limits, as this has a direct impact on the design of other components connected to the high voltage bus. Typical approaches attempt to reduce the required DC-link capacitance by increasing the pulse width modulation (PWM) switching frequency. However, this leads to a compromise as higher switching frequencies can cause additional losses, potentially necessitating a larger area for costly silicon carbide (SiC) semiconductors. In this contribution, optimized pulse patterns (OPPs) are proposed as a solution to improve the DC-link voltage ripple, allowing a reduction in capacitor size and a significant decrease in switching frequency compared to the standard Space-Vector PWM. The paper outlines the mathematical methods for simulating and designing the DC-link regarding voltage ripple and current stress. It compares the simulations for Space-Vector PWM and OPPs, leading to the development of two distinct capacitor designs. The theoretical 20% reduction in the volume of the DC-link capacitor is confirmed through experimental validation on a 250 kW machine test bench setup.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"5 ","pages":"1767-1781"},"PeriodicalIF":5.0,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10746599","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142672060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
