The integration of a super-lift cell not only enhances the voltage conversion ratio but also significantly reduces the voltage stress on the switching device. A comprehensive steady-state mathematical analysis is conducted to highlight the key features of the proposed topologies and is followed by a detailed comparison with existing Z-source converter configurations. In addition, small-signal modeling of the enhanced SuLZSDC topology is carried out to analyze system dynamics and facilitate the design of a proportional–integral (PI) controller for output voltage regulation and stable closed-loop operation. To validate the theoretical findings and demonstrate the high-gain performance, a 400-W laboratory prototype is developed and tested.

To address this issue, this study proposes a grid-impedance-estimation-based linear active disturbance rejection control strategy (GIE-LADRC). This method integrates the online estimated grid impedance into the design of the linear active disturbance rejection control (LADRC) compensation factor, enabling the factor to better approximate the actual system gain under impedance variations in weak grids. This enhances the ability of the linear extended state observer (LESO) to observe and suppress disturbances caused by impedance. In practice, LADRC first provides approximate decoupled control of the dq-axis currents. Subsequently, under this decoupled condition, a reactive power variation strategy that maintains a constant <inline-formula> <tex-math>$d$ </tex-math></inline-formula>-axis current reference is employed to obtain an online estimate of the equivalent grid impedance, which has minimal impact on the converter’s active current output during the estimation process. The stability of the proposed method under the complete current control framework is evaluated through impedance model-based stability analysis. Finally, experimental results from a 4 kW prototype confirm that GIE-LADRC can maintain high-quality current output even in very weak grids with an SCR below 2.","PeriodicalId":13093,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Power Electronics","volume":"14 5","pages":"6433-6444"},"PeriodicalIF":5.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article introduces a nonisolated modular multilevel DC–DC converter that achieves a substantial voltage step-up using a chain of identical submodules (SMs) arranged symmetrically to maintain uniform device stress and inherent power sharing. The structural symmetry naturally produces interleaved switching patterns, leading to reduced output ripple without requiring additional control overhead. A relative-voltage control approach with a zero reference further limits the number of sensing and feedback loops, enabling practical scalability to higher level configurations. Steady-state analysis is used to obtain expressions for voltage gain, inductor current ripple, and capacitor voltage ripple, clarifying the influence of design parameters. The architecture is well-suited for renewable-energy sources requiring medium and high-voltage DC interfacing. Experimental results from a laboratory prototype confirm accurate gain regulation, low output ripple, balanced submodule operation, and stable dynamic behavior, demonstrating the feasibility of the proposed architecture.","PeriodicalId":13093,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Power Electronics","volume":"14 5","pages":"5499-5512"},"PeriodicalIF":5.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147361045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the analytical expression for the output voltage power spectral density (PSD) of RSP-SVPWM in a two-level PMSM system is derived, and the impact of different carrier switching frequency (CSF) probability density functions (PDFs) on the distribution of HFSVH is clarified. Second, to address the limitation that under uniform distribution, HFSVH energy concentrates around the CSF, and a single Beta distribution cannot effectively suppress the HFSVH, while adjusting the frequency band, MDBORSP constructs a dual-Beta distribution with a region overlap mechanism. This approach effectively reconstructs the HFSVH spectrum, significantly enhancing harmonic suppression performance. Furthermore, a three-state Markov chain is introduced to establish a harmonic distribution control mechanism, using asymmetric CSF PDFs to regulate the HFSVHP frequency band while maintaining strong harmonic suppression. Simulation and experimental results show that, compared to traditional SVPWM, MDBORSP improves HFSVH suppression by 21.25 and 19.83 dB, respectively, and achieves controllable migration of the harmonic peak frequency band. Additionally, the algorithm requires only <inline-formula> <tex-math>$14.79~mu $ </tex-math></inline-formula>s per switching cycle, providing ample real-time implementation margin.

However, current designs with ground fault suppression capabilities often suffer from limitations such as limited functionality, high implementation costs, and a lack of consideration for voltage drops caused by line impedance or load variations. An adaptive fault current control method for active compensators is proposed in this article, through which automatic switching between voltage suppression and current suppression principles is achieved. The suppression effectiveness for ground fault currents is less susceptible to grounding parameters and load variations. Furthermore, an active compensator topology is presented, where the common point of the three-phase active compensator is connected in series with a passive voltage feedback transformer. This design enables the implementation of the proposed fault current detection and suppression method and integrates power compensation functionality. Additionally, the requirement for an additional DC power supply for the grounding arm is eliminated, thereby reducing the overall system cost. Finally, simulations and experiments confirm that the proposed active compensator structure and control strategy not only achieve both fault suppression and power compensation but also demonstrate superior fault suppression performance and reduced overall costs.","PeriodicalId":13093,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Power Electronics","volume":"14 5","pages":"6611-6624"},"PeriodicalIF":5.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148289222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
