This work focuses on a family of DP-VSC based single-stage AC-DC converters that deliberately multitask a high-frequency transformer (HFT) such that the primary side windings carry both low and high frequency (HF) currents. The low frequency components correspond to the ac grid currents that do not generate any core flux while the HF currents are exploited for power transfer via transformer action. Quasi-square HF differential voltages can be synthesized across the primary HFT windings to yield HF trapezoidal currents, all the time guaranteeing zero common-mode winding voltages. Recently, the authors proposed a discontinuous pulse-width modulation scheme, termed FDPWM1, that satisfies all these objectives to allow use of a compact 3-limb HFT in comparison to prior art that relied on collectively bulkier three single-phase HFT units. Building upon our previous work that introduced FDPWM1, this article presents an in-depth analysis of its performance characteristics across a broad range of operating points.

The core contribution lies in the real-time optimization of the MPC weighting matrices through a Genetic Algorithm (GA) executed on a remote server, while the converter operates on a physical experimental platform. The proposed IoT-based framework enables bidirectional data exchange, where real-time voltage and current measurements from the solar plant are used to evaluate the GA fitness function, and the optimized control parameters are transmitted back to the controller. This approach mitigates modeling inaccuracies and parameter uncertainties commonly associated with offline and simulation-based tuning methods. Experimental results obtained using a solar development kit demonstrate that the proposed method significantly improves dynamic performance, achieving reduced overshoot and settling time when compared with deterministic MPC tuning and conventional control strategies, including SMC, SM+PI, and 2P2Z controllers. The results confirm the effectiveness, robustness, and practical feasibility of combining predictive control, evolutionary optimization, and IoT connectivity for high-performance control of PV power converters.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"976-987"},"PeriodicalIF":3.9,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11417724","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147557473","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 proposed approach minimises computational burden to 44.6% unlike PTC, and also was compared to the predictive current control (PCC). Experimental results at 1345 rpm and 60% load demonstrate that the proposed PTC-LA achieves a 19.44% torque ripple and steady-state speed error of 4.3 rpm, outperforming both conventional PTC and PCC. Under parameter mismatch conditions at low speed, the PTC-LA maintained a speed error below 5.9 rpm and a torque under 0.28 Nm.

This requires innovative thermal management solutions to handle the power density growth. In this scenario, a real time estimate of the transistor junction temperatures avoids overheating issues, increasing the converter reliability. While a direct measurement is often not feasible, an indirect temperature estimate can be obtained with temperature-sensitive electric parameters (TSEPs). Adopting this technique usually requires an extensive individual characterization of each power device, involving laboratory equipment and thus limiting the method adoption. This article presents a complete solution to accurately characterize the chosen TSEP, adopting a fully in-circuit technique and a custom active gate driver (AGD). This method extracts the required characteristics from each power device, using only the hardware resources of the power converter. The proposed procedure manages the entire calibration process, dealing with device heating, measurement, data collection and synthesis of the temperature estimation model. The authors aim to make the proposed method suitable for a production environment, boosting the adoption of TSEP-based techniques in commercial converters. In this article the proposed procedure is leveraged to characterize and use the on-state resistance TSEP for online estimation in discrete silicon-carbide MOSFETs, although its applicabilityto other TSEPs and devices is also discussed. Finally, extensive experimental testing is conducted to evaluate the method effectiveness.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"1830-1845"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11557192","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148433131","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 proposes a new inductive and capacitive combined hybrid wireless power transfer coupler for UAV. Among them, the capacitive coupler is designed as a six-plate structure. A receiving plate and a shielding plate are installed on each of the two landing gears of the UAV, and the transmitting plates are installed on the ground. The FR4 epoxy insulating material is filled between the plates to increase the coupling capacitance. The inductive coupler adopts a square coil form, which is installed on the belly of the UAV. Inductive coupler and capacitive coupler compensate each other for reactive power while transmitting power, which eliminates the need for additional compensation network components on the receiving side. Secondly, based on the single-sided LCLC compensation network, this paper presents a parameter design method that can adjust the power transmission ratio of inductive and capacitive couplers. Then, the component stress analysis was conducted. Compared with the inductive power transfer (IPT) and capacitive power transfer (CPT) systems that have the same coupler and similar compensation network, the proposed system significantly reduced the stress on the coupler. Finally, an experimental prototype is established to verify the scheme. The experimental results show that the system can transmit 500 W at an efficiency of 80.7%, which means it can be used for wireless charging of UAV.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"316-329"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11348946","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148486394","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}

To harness this benefit in converters conventionally implemented with inductors at the output, an input passive network consisting of two inductors and a bypass capacitor can be utilized instead of the output inductor. This work focuses on the current-sourced buck converter (CSBC), the most fundamental two input inductor topology, and presents a comprehensive analytical model for the bypass capacitor voltage and input inductor currents. In addition, an analytical expression for the output voltage is derived, demonstrating its dependence on not only the duty ratio but also the switching and resonant frequencies of the CSBC. The analysis is expanded from an uncoupled CSBC to include magnetic coupling between the input inductors, which enables the CSBC to be implemented with only one magnetic core. The effects of coupling are thoroughly analyzed, including the potential to reduce passive component volume. The proposed model is validated through simulation and experimental results for a design example. Design insights are provided to guide passive component value selection, evaluate switch stress based on capacitor voltage and inductor current ripples, and identify operating conditions where magnetic coupling may be beneficial in reducing passive component volume.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"1992-2013"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11558130","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148486416","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}

Compared to conventional active-switched qZSI structures with an identical number of passive and active components, the proposed topology provides a significantly improved voltage gain, particularly in the low shoot-through duty ratio region. Key advantages of the proposed design include continuous input current, reduced voltage and current stresses on both active and passive devices, and high conversion efficiency. Furthermore, unlike the conventional Z-source inverter, the proposed configuration eliminates inrush current at startup and exhibits a low input current ripple. Additional benefits include the presence of a common ground between the input source and inverter legs, reduced size of the impedance network inductors and capacitors, and enhanced output voltage quality enabled by the use of a higher modulation index. The paper presents the operating principles, a detailed theoretical analysis, and comparative performance evaluation against conventional counterparts in terms of voltage gain, component count, and voltage/current stresses.
