Compared with the existing research that simplifies SiC MOSFET model in the RTS implementation process, the proposed modeling method not only considers the hard-switching process caused by insufficient deadtime, and the special switching mode that the channel turn-off precedes the antiparallel diode turn-on in opposite device, but also fits the nonlinear characteristics of the SiC MOSFET through look-up tables (LUTs). In addtion, the parallel solution structure of the FPGA-based RTS model is completed through hardware optimization design scheme. Combined with circuit decoupling technology, the model can be solved by the Backward Euler (BE) discretization method with time-step of 10 ns.

However, 3L modulation makes it difficult to address the requirement of a wide output voltage range. Therefore, this paper presents a hybrid modulation method for the DNPC-LLC converter, incorporating the traditional 3L modulation and a proposed two-level (2L) modulation, which allows lower output voltages, reduces the switching frequency and the number of switching operations of the primary-side switches. Furthermore, the operating principles and voltage gains of both modulation methods are analyzed. Finally, a 3.7 kW SiC-based DNPC-LLC converter with synchronous rectification at an 800 V input is implemented. The output voltage ranges from 20 V to 450 V, and smooth transitions between different modulation modes are verified. The proposed converter achieves a maximum efficiency of 97.3% at an output of 360 V and 10.3 A. Furthermore, compared to the 3L method, the 2L method improves efficiency by at least 0.5% when the output voltage is below 200 V. Additionally, the voltage balance between two series dc-link capacitors is fulfilled after applying voltage balancing control.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"354-370"},"PeriodicalIF":5.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10878305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480802","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 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.

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}
