However, existing converters suffer from either low voltage gain or a higher component count. Therefore, this article proposes a MPPT-enabled <italic>LnC2<italic>n-2 network-based high-gain modular dc–dc converter capable of achieving high gain and maximum power from PV by utilizing fewer components. In the proposed <italic>LnC2<italic>n-2 network, <italic>ncorresponds to a number of stages, and each stage of the network comprises two capacitors, one diode, and one inductor. The proposed converter is expandable by increasing the number of stages and provides higher gain at a lower duty ratio with increasing <italic>n. Basic <italic>L3<italic>C4 modular topology for <italic>n= 3 is formulated and is analyzed in both continuous conducting mode (CCM) and discontinuous conducting mode (DCM). Further, an incremental conductance algorithm is applied for MPPT operations to verify the integrability of the converter with PV. The converter is also evaluated against different existing converter topologies concerning voltage gain, switches, and overall component count. A 300-watt experimental prototype is developed for <italic>n= 3 to verify the proposed converter in CCM, DCM, and MPPT operation with the help of a PV emulator and TI F28335 microcontroller. The proposed topology for <italic>n= 4 has also been validated in CCM to demonstrate the converter's modularity.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"677-686"},"PeriodicalIF":0.0,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To support the electrical grid by eliminating frequency disturbances and also provide inertia to the power system, the output power of PV systems can be controlled by applying a flexible power point tracking (FPPT) technique, where the PV array output power is continuously regulated to the desired reference value. Since PV modules frequently operate under partial shading conditions (e.g., due to nearby objects in building-integrated PV applications, deposition of dust etc.), the FPPT algorithms designed for operation of the PV system under uniform incident solar irradiance cannot operate efficiently. Therefore, the concept of the global FPPT (GFPPT) has been introduced. In this article, a novel GFPPT algorithm based on machine learning is proposed. By utilizing the proposed Q-learning algorithm, the GFPPT system is able to obtain knowledge over time, in order to achieve faster convergence. The experimental results demonstrated that the proposed GFPPT algorithm converged in significantly less time compared to past-proposed GFPPT methods, while achieving an almost same steady-state tracking error.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"699-710"},"PeriodicalIF":0.0,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The detrimental impact of crosstalk can result in device malfunction or failure. In this article, a model of the phase-leg structure emphasizing parasitic elements is introduced. Subsequently, the mathematical model of the circuit is deduced, followed by an investigation into the impact of low-side insulated gate bipolar transistor (IGBT) gate resistance and the sensitivity of low-side switch emitter inductance. We explored in this article that in the inductive load switching a negative spike also happens in the lower device gate terminal during the crosstalk prior to the positive spike. This negative spike can be harmful for the gate oxide insulator of the device. For optimal outcomes, a double-pulse test is set up. This test entails the application of two closely spaced voltage pulses to a device, allowing the assessment of its switching characteristics in inductive loads. Furthermore, while examining the impact of low-side device gate resistance on crosstalk, the influence of low-side switch parasitic emitter inductance becomes evident, and the optimal values for these parameters are determined.

The WFFSM also provides an integrated stator structure that accommodates both field and armature windings, while the rotor does not require windings or magnets. However, having both windings on the stator creates long and inefficient magnetic flux paths at specific rotor positions that do not directly contribute to electromagnetic torque generation. Therefore, it is imperative for WFFSMs to thoroughly investigate the magnetic flux paths associated with the stator bridge structure. This article employs a multi-segment magnetic equivalent circuit to identify these longer magnetic flux paths, validated through finite element analysis. In addition, their impact on inductance and torque production of WFFSMs with different winding configurations as well as stator-rotor pole combinations. Torque segregation and energy conversion loop analysis are conducted to visualize and quantify the impact of the longer magnetic flux paths on electromagnetic performances. The study reveals that the inductance harmonics originating from the integrated stator structure generate a negative reluctance torque, decreasing the net output torque. The results demonstrate that the WFFSM employing a circumferential field and armature winding configuration, which does not suffer from the longer magnetic flux path, achieves the highest output torque. It exhibits an output torque 57% higher than the WFFSMs suffering from the longer magnetic flux path, with identical volume.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 3","pages":"888-899"},"PeriodicalIF":0.0,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The O and XY coils, representing planar and crossed-dipole coils, are coaxially stacked and naturally decoupled by sharing a common ferrite core to form a compact OXY receiver. Accordingly, a 500 W experimental prototype is developed to verify the effectiveness of the proposed system under different loads. The measured transfer efficiency of the proposed magnetic coupler can reach up to 64.86% at the misaligned distance of 150 mm, marking a 17.34% improvement of average efficiency than the traditional O-to-O magnetic coupler across the entire misalignment range. Additionally, the transfer power can be maximally increased by up to 200 W.

This article investigates the stability of high-power GCI controlled by MPC and its application in offshore wind farm. The frequency scan technique is employed to derive the impedance characteristic of MPC-enabled inverter. Then, effects of MPC parameters and operating conditions on passivity are investigated.

As with the growing trend of EVs, their widespread use may compromise grid quality, leading to the demand for a stable, simple, and better control system. However, some controllers provide sluggish responses and fail to compensate for harmonics. Therefore, to mitigate the grid current harmonics, a repetitive controller (RC) has been analyzed. Within a specified integer period, for any periodic signal, the RC may accomplish tracking of zero steady-state error. However, if grid frequency varies under the permissible range the performance of conventional RC degrades. Therefore, a Lagrange interpolating polynomial-based fractional-order RC has been implemented with a fixed sampling rate to enhance its performance during frequency fluctuations. PLL estimates the frequency, which is fed back to update the controller's resonant frequency. Then, using Lagrange interpolating the polynomial the fractional delay is approximated. The proposed controller has been designed within a MATLAB environment. Its performance has also been probed in a real-time experimental setup with OPAL-RT (4510).","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"72-81"},"PeriodicalIF":0.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
