In the proposed Increased Input Range Synchronized Switch Harvesting on Inductor (IIR-SSHI), once the SSHI scheme stops operating because of the change in the excitation amplitude, a low-power peak detector is activated to accumulate the charge of the parasitic capacitance of the PEH by successive bias-flipping actions, without requiring any external energy investment, i.e., energy kick start. Therefore, the proposed circuit can autonomously maintain the energy extraction procedure active at the highest performance of energy extraction, i.e., FoM<sub>MOPIR</sub>, when the excitation amplitude is reduced considerably. The proposed circuit is simulated and verified using a 0.18-μm CMOS standard technology, ensuring energy extraction performance and robustness. Based on the post-layout simulation results, the proposed circuit can extract energy from PEH significantly for a minimum input excitation amplitude of only 800 mV. The maximum output power improvement relative to the Standard Energy Harvesting (SEH) and standard SSHI circuits is 5.5 and 2.75 in decreased input amplitude scenarios, respectively.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"314-326"},"PeriodicalIF":5.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10856550","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455323","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}

Connecting cells in series, parallel (2 Dimension-2D) to the MMC allows easy adjustment of the power and output voltage. The design of MMCs must ensure that the switching voltage is less than the switching voltage limit of the insulated gate bipolar transistor (IGBT), and that the 2D structure can easily adjust the voltage at each level by adding or removing several cells in series. A 2D structure can be designed for a wide power range, which can be quickly achieved by adjusting the number of cells (or multicell branches) in parallel. Currently, the use of 2D structures has only a few published studies on the aspect of DC/DC modulation. This study implements a decentralized carrier phase angle shift algorithm for multicell power converters coupled in series and parallel to supply single-phase alternating current (AC) loads. This paper proposes and verifies an algorithm to ensure that the carrier phase angles of cells in the 2D structure are evenly alternating, thereby improving the algorithm to balance the alternating current between parallel branches connecting the load. Reviews, analyses, and assessments were verified on a 2D structure simulation model including six parallel branches, each of which has six cells in Matlab/Simulink software, and verified by an experimental model including four branches, each of which has four cells using digital signal processing (DSP) TMS320F28379D as the controller.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"243-265"},"PeriodicalIF":5.0,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10840202","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106171","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 issue becomes more challenging with the implementation of SiC devices because their smaller die size reduces the thermal inertia and increases the thermal resistance. This paper explores the potential of utilizing vapor chamber (VC) through near junction integration inside a SiC power module to reduce junction temperature swings. A novel fabrication process enables the near junction integration of VC which not only acts as heat spreaders but also conducts the drain current of MOSFETs. The thermal impedance analysis in the frequency domain highlights VC's strong attenuation effect on medium frequency thermal cycles, which are particularly damaging to power modules. Two case studies are performed to evaluate the thermal performance of VC integrated module in traction inverter applications. Both simulations and experiments demonstrate the effectiveness of integrating VC: more than 33% reduction in maximum junction temperature and 44% reduction in junction temperature fluctuation. Time constant spectrum analysis further reveals that the VC module's superior thermal performance stems from its ability to minimize thermal resistance components with short time constants, a benefit that is unique to near-junction thermal management","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"286-299"},"PeriodicalIF":5.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10839392","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388639","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 approach has been introduced in previous works, which discussed the overall objectives, scope of application and the modeling methodology for switched-mode power converters. However, a systematic validation of the system model's behavior remains outstanding. The research presented in this work addresses this gap by detailing and applying the methodology and comparing simulation results with measurements from a DC system. The findings reveal that the grid models adequately represent the system's actual behavior and render the simulation results useful for simulation-based system analysis. Discrepancies arise from an insufficient modeling of the system's damping elements. These differences however fall within acceptable error margins, especially in the context of system stability analysis. Despite the need for further verification, this paper demonstrates the approach's potential and facilitating the development of versatile component libraries and hence design tools for DC systems.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"228-242"},"PeriodicalIF":5.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10839307","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106737","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 measurements are performed with a DC-link voltage of 800 V at peak collector current of 14 A. A range of base currents modulated by base resistors are employed with two load inductors to enable a wide range of switching conditions at different switching rates. The TCAD model is validated by comparing with datasheet while double-pulse switching events have delivered the experimental switching transients. In the Silicon BJT case, the device is shown to exhibit very significant turn-off delays compared to 4H-SiC BJTs, particularly under high-level injection conditions. The absence of delay in 4H-SiC BJTs is due to the lower minority carrier lifetime and thinner base region, enabling higher DC gain and significantly faster transients. However, the current drop phenomenon is clearly seen in the 4H-SiC BJT in both measurements and TCAD modelling, which unlike the Silicon, is very sensitive to the peak collector current at HLI for a fixed base current due to its thinner base and more susceptance to the Early effect. The Silicon BJT does not exhibit such trend, given its wide base region, though its inability to eliminate the depletion regions at on-state with HLI is demonstrated by rise of voltage while still conducting, as demonstrated by TCAD and measurements.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"162-175"},"PeriodicalIF":5.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10833858","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106735","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 tackle this challenge and enhance the dynamic response of HμGs, PID based model reference adaptive control (MRAC), for the synchronous generator (SG) is applied in this paper. Also, the effect of ESSs on enhancing the system dynamic performance is investigated. The emergence of super capacitor (SC) is suggested to emulate the dynamic inertia response. The SG's adaptive control enables immediate modifications to optimize HμGs frequency, while the rapid response of ESSs stabilizes and supports power generation variations to operate HμGs steadily and overcome the problem of interruptions between load and supply. These combined technologies work together to enhance the dynamic stability of the proposed two-area HμGs system during standalone operation. Advanced metaheuristic optimization techniques are utilized to determine the optimal gains for SC and battery controllers, as well as for MRAC of SG. The obtained results prove the efficacy of the super capacitor and the proposed adaptive control strategy in improving the frequency of HμGs during standalone operation.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"196-211"},"PeriodicalIF":5.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10833776","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143106733","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}
