Such optimization requires fast and accurate electric field computations in several critical regions of the MFT, making the choice of effective computation methods essential. This paper compares suitable methods, including the Schwarz-Christoffel transformation (SCT), the charge simulation method (CSM), and commonly used analytical approaches, by benchmarking them against nearly 4000 finite element analysis (FEA) simulations. Each method's error is analyzed, and a sensitivity study is performed to define the parameter ranges where each method yields accurate results. The CSM is found to provide the most accurate field computation (<inline-formula><tex-math>$< $</tex-math></inline-formula>5% error) across all examined critical regions. However, to compensate for its increased computation time for geometries with rectangular conductors, combining the CSM with the SCT – which is approximately 10 times faster – is recommended to achieve optimal performance.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"630-646"},"PeriodicalIF":5.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10938224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845570","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}

Using a multivariable design framework, this paper presents small-signal and large-signal design techniques for an SCB converter under one-degree-of-freedom (1DOF) and two-degree-of-freedom (2DOF) CMC implementations. In the 1DOF case, only the primary phase inductor current is sensed, whereas both inductor currents are sensed in the 2DOF case. The 2DOF design technique achieves robust compensation with fast recovery and a well-damped response. Furthermore, it is demonstrated, for the first time in an SCB converter, that employing a single voltage controller with optimal gains allows the large-signal design technique to achieve near-time-optimal recovery within the series capacitor voltage constraint while maintaining stable periodic behavior. A comparative case study highlights the effectiveness and superiority of the proposed design techniques over existing linear and nonlinear control methods.

A large magnitude reactive droop coefficient (RDC) can decouple the frequency and voltage droop loops. However, the large droop coefficients can lead to increased power oscillations and insufficiently damped modes in the system. To balance these conflicting objectives, this paper proposes an adaptive droop control strategy that adapts the RDCs in real-time, ensuring the best possible reactive power sharing while maintaining sufficiently high damping of the inverter's oscillatory modes. The damping-ratio is derived by perturbing the RDC and processing the inverter's active power response using the Matrix-Pencil mode estimation algorithm. The proposed control system is validated through Controller Hardware-in-the-Loop (C-HIL) experiments. Typhoon HIL-402 real-time (RT) emulator is used to emulate the power stage. A dedicated Windows PC serves as the secondary controller, updating the reactive droop coefficient. Communication between the hardware emulator and the controller takes place over the OPC UA protocol via a LAN. The results demonstrate that the proposed control offers three key advantages: (i) improved reactive power sharing compared to the fixed droop control method, (ii) enhanced microgrid stability under various disturbances, and (iii) applicability to grids with unknown grid <inline-formula><tex-math>$R/X$</tex-math></inline-formula> ratios.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"613-629"},"PeriodicalIF":5.0,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10925905","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839913","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}

This has posed significant challenges to traditional grid-following control strategies, resulting in increased grid harmonics, heightened instability risks, and frequent power generation system failures. In contrast, grid-forming control strategies, which provide active voltage support, have demonstrated superior stability in weak grid conditions. However, neither grid-following nor grid-forming control strategies alone can comprehensively meet the requirements of power systems in terms of stability, economic efficiency, and grid support. To address these challenges, this paper proposes a model predictive control (MPC) strategy that integrates grid-following and grid-forming control. First, a mathematical model of the grid-connected inverter is established, and stability analyses are conducted for both grid-following and grid-forming modes. Second, model predictive control algorithms are thoroughly investigated for both modes, and an optimized control strategy is selected through comparative analysis. Finally, the effectiveness of the proposed strategy is validated using a hardware-in-the-loop (HIL) simulation platform. Experimental results demonstrate that the proposed method significantly enhances the stability of grid-connected inverters under conditions of significantly increased grid impedance and reduced SCR, ensuring reliable operation of power systems. This approach holds substantial practical application value for modern power systems.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"909-918"},"PeriodicalIF":5.0,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11003414","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170857","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}

Consequently, the development of GCCs with higher power, lower cost, and higher performance has become a hotspot in international power electronics research. However, classical GCC technical solutions struggle to meet the trade-offs between multiple performance indicators, including reliability, operating efficiency, power density, power quality, response speed, and cost. To address these issues, an emerging technology involves hybridizing Si and WBG devices in one equipment to combine the high current and high cost-effectiveness of Si inverters with the excellent switching performance of WBG inverters. In this context, this paper reviews in detail the inverters based on hybrid devices (HyDs) and hybrid systems (HySs), which are the two mainstream implementation schemes of Si/WBG hybrid inverters. The latest research on these hybrid inverters is systematically summarized, covering basic principles, hardware design methods, control and optimization strategies, and representative laboratory prototypes.

Known for its low on-resistance, high switching performance, normally-off operation, and reliability, DDD GaN devices are becoming popular in power applications. In this work, an in-house D-mode GaN HEMT with a blocking voltage of 200 V and on-resistance of 18 mΩ is used in a short-pulse laser driver for the optical phased array (OPA) applications. To achieve higher spatial resolution, the laser repetition rate must be in the tens of MHz range. Therefore, the dynamic behavior of device is first characterized by the double-pulse test. Additionally, the push-pull based laser driver actively controls the load capacitor charging time and the laser pulse width, thereby ensuring stable operation at high repetition rates. The output characteristics of switch-controlled (SC) short-pulse laser driver are simplified to switch turn-on time, stray inductance, and the input voltage. Finally, the experimental results achieved a short pulse width of less than 5 ns, high repetition rate of 50 MHz, propagation delay of less than 1.5 ns and peak power of 175 W, meeting the requirements for the specified object detection application.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"474-484"},"PeriodicalIF":5.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10921718","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748929","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}

This paper analyzes the impact of such delays on PV park stability under a centralized secondary voltage controller (SecVC) and proposes a local control strategy to enhance coordination robustness to CDs. A nonlinear model of a PV park is built and used for small-signal stability analysis, incorporating Monte-Carlo Simulations (MCS) to assess the impact of stochastic delays, alongside time-domain simulations to evaluate dynamic responses.
