The objective of this robust control approach is to mitigate cross-coupling challenges inherent in MIMO systems and effectively manage the parametric uncertainties associated with the converter as well as input and output disturbances. To achieve this objective, the paper begins with deriving the general nonlinear dynamic equations of an n-level step-up multi-port DC/DC converter (<inline-formula><tex-math>${MPDC}_{nL}^{SU}$</tex-math></inline-formula>). Subsequently, for a case study involving a 3-level step-up multi-port DC/DC converter (<inline-formula><tex-math>${MPDC}_{3L}^{SU}$</tex-math></inline-formula>) the equations are linearized to obtain the state-space model. Following the derivation of the converter model, a controller comprising two control loops is designed. The outer loop, responsible for regulating the voltage of output ports, is synthesized through a robust μ-optimal method using the <inline-formula><tex-math>${D} - mathcal{G} - mathcal{K}$</tex-math></inline-formula> iterative procedure, while the inner loop, responsible for regulating the current sharing among the parallel modules and generating PWM signals, is stabilized via multiple PI controllers. Finally, hardware-in-the-loop (HIL) test results derived from OPAL-RT 4610, and experimental results from a prototype are used to validate this control approach. The proposed decoupled mixed <inline-formula><tex-math>${mu }$</tex-math></inline-formula> synthesis method ensures robust performance and stability and results in a less conservative controller design for the <inline-formula><tex-math>${MPDC}_{3L}^{SU}$</tex-math></inline-formula>.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"300-313"},"PeriodicalIF":5.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10878119","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455322","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 system comprises 1) a machine-side vector-controlled CSC to regulate the power extracted from the permanent-magnet synchronous generator-based wind turbine, where a practical two-mass drivetrain model is adopted, and 2) a grid-side CSC controlled by a GFM scheme to support the grid and regulate the dc-link current to maintain a stable delivery of the extracted wind power. A detailed small-signal state-space model of the overall CSC-based system is developed to investigate the system's stability under different practical parameters, such as wind power reserve, control parameter, and short-circuit ratio variation. The equivalent dc-side impedances of the grid and machine-side CSCs are also developed and used to characterize the dc-link stability using the Nyquist stability criterion. A systematic design approach for the control parameters is presented. Nonlinear-model time-domain simulations are presented to verify the analytical results and assess the performance under various operating conditions, such as grid disturbances, faults, and parameter uncertainty. This study shows that the GFM CSC system provides stable operation under weak and very weak grid conditions and robust performance under fault conditions compared to a similar GFM voltage-source converter system.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"327-343"},"PeriodicalIF":5.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10870106","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455233","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}

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.

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}

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.

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.

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}
