The steady-state error is analyzed in detail, considering model parameters and modeling methods. We establish a unified and simplified predictive model that is suitable for different dual-active-bridge topologies, reducing dependence on model parameters and computational burden. To mitigate sensitivity to sampling noise, we design a noise tolerance enhancement strategy by redefining a coefficient in the simplified model. This strategy expands the noise tolerance range while maintaining excellent dynamic performance, low system cost, and computational burden. The proposed control strategy is verified by using an experimental platform with TMS320F28379D as the core controller. Results show that our strategy effectively reduces sensitivity to model and noise while ensuring excellent dynamic performance compared to traditional model predictive control. The strategy is universal and significantly reduces the computational burden.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 3","pages":"270-281"},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11045855","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236636","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}

Moreover, it results in a situation where it becomes difficult to maintain high-quality power in the distribution sectors. As a result, it is exceedingly challenging to maintain a high standard of power quality (PQ) in a distribution system. To improve the quality of grid voltage a series compensating filter called dynamic voltage restorer (DVR) is used in this suggested work. An adaptive zero-attracting quaternion-based least mean square (AZQLMS) approach is suggested to extract the fundamental quantity from the polluted voltage of the grid. An optimization technique, frilled lizard (FL) inspired by nature, is employed to estimate the gains of the fractional order proportional integral derivative (FOPID) controllers used in this control algorithm for DC link voltage stabilization. Compared to the marine predator (MP) optimizer, the proposed Frilled Lizard algorithm demonstrates enhanced capability to escape from local entrapment with quicker convergence and also reduces the complexity of manual tuning effort simultaneously. From the perspectives of DC link time response characteristics under transitory scenario, control technique, and the range of compensated voltage, the enhanced DVR's principle has been examined. By minimizing the voltage issues and the voltage total harmonic distortion (THD) at the connection point below 5%, both controllers were able to restore the voltage magnitude. MATLAB/Simulink with experimentation work is utilized to analyze the efficacy of the suggested approach. It is evident from the information that the AZQLMS and FL-FOPID successfully control the distribution grid's voltage.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 3","pages":"296-303"},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11045851","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236654","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}

Conventional redundant method by bypassing whole SMs at ac-side may lead to insufficient modulation ratio margin and waste the potential of healthy H-bridge part. First, the comparison of ac-side bypassing submodules (SMs) with dc-side disconnecting cluster is made; and the concept of new battery cluster fault tolerance strategy is discussed. In order to give full play to the grid voltage support capability of the faulty module, a battery cluster fault tolerance operating control combining proposed fault-tolerant strategy and optimal zero sequence voltage injection is proposed in this paper. As a result, it can effectively enhance the capability of handling battery warnings and failure and is able to tolerate any number of faulty battery cluster modules. Besides, state of charge(SOC) balancing of healthy SMs and capacitor voltage balancing of faulty SMs are incorporated into control algorithm. At last, effectiveness of the proposed battery fault tolerance strategy is thoroughly verified in BESS of 10 kV/5 MW and 14 SMs per phase by MATLAB/Simulink simulations and hardware-in-loop experiment.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 2","pages":"141-152"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970400","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557719","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 some special applications, the RSC TLI should be operated with simultaneous lower common-mode voltage (CMV) and unbalanced neutral-point voltage (NPV) conditions. For this reason, this article further proposes a space vector modulation (SVM) strategy that fulfills the above requirements. First, the basic vectors with low CMV amplitudes are selected, and four basic vectors are employed to synthesize the reference vector and achieve NPV flexible control. The duty cycles of the employed basic vectors are obtained by a novel indirect method, and the appropriate switching sequences are designed to further reduce the current harmonic and keep lower switching losses. Finally, the separate control of capacitor voltages is achieved by using a closed-loop control approach to optimally regulate the duty cycles of different basic vectors. Compared with the conventional strategy, the proposed scheme can reduce the CMV magnitude by half and is applicable to unbalanced NPV conditions. The feasibility and effectiveness are verified by experiments.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 2","pages":"130-140"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970398","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557720","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 M-V2G operates in four modes, namely (A) active power injection (API), (B) API and SC, (C) API and partial SC, and (D) SC. The proposed FAC extraction method involves processing the <tex>$d$</tex>-axis current of non-linear load through the cascaded band-stop filter. The resulting signal comprises a dc and an ac component with six times the fundamental frequency. For balanced currents, FAC is derived as the value of this signal sampled at the absolute peak value of its derivative. For unbalanced load currents, FAC extraction considers (i) the average of six consecutive samples, or (ii) inclusion of an additional BSF with a center frequency corresponding to the 6<sup>th</sup> harmonic is included. The second option provides a faster dynamic response. M-V2G interface is controlled based on the FAC and commanded API. The proposed technique ensures accurate FAC estimation without complex computations, as evident from the pseudo-code and experimental studies. Further, the experimental results confirm its effectiveness, feasibility, and practical viability. The M-V2G interface with the proposed FAC estimation scheme increases power quality and VA utilization of the V2G interface.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 2","pages":"153-161"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970397","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557661","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 paper proposes a novel static identification method for both the inductance parameters and rotor initial position of a permanent magnet synchronous motor, to achieve simultaneous identification of both parameters. The method involves the injection of high-frequency quadrature voltage signals into the motor, followed by the decomposition of the high-frequency response current using the recursive least squares method. This results in the identification of the motor inductance parameters and rotor initial position, based on the outcomes of the motor rotor polarity identification. Compared with traditional methods, this approach has the advantages of eliminating the delay effect of digital system sampling and control, and of not requiring filters to demodulate the high-frequency response current. Furthermore, the identification results are less affected by the nonlinearity of the inverter. Both simulation and experimental validation support the validity of the method. The experimental results demonstrate that the errors between the identified values of the inductance of the cross and straight axes and the design value are 0.15% and 0.97%, respectively. Additionally, the deviation between the identified results and the actual value of the initial position of the rotor is 1.76°, indicating a high level of identification accuracy.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 2","pages":"198-209"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970396","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557715","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}

Among the various control strategies for DAB converters, the triple-phase-shift (TPS) control is recognized for its effectiveness. In this article, a soft-switching control method based on TPS control is proposed, which is advantageous for enhancing the efficiency of the DAB converter over the full power and wide voltage regulation range. First, the twelve operating modes of the DAB converter are categorized. And then an innovative methodology is introduced, wherein the DAB converter is equivalently transformed into a four-switch buck-boost (FSBB) converter by decomposing the midpoint voltage waveforms on both the primary and secondary sides. On the basis of the equivalent circuit, a hybrid phase-shift control method based on the soft switching is proposed, which delineates the DAB converter into six operating modes. To secure smooth and seamless transitions between these modes, a unified uni-variate control method is presented, which is simple and readily implementable. Ultimately, a 2.5 kW prototype is constructed, and the correctness and effective-ness of the proposed method are validated via the experimental results.","PeriodicalId":100339,"journal":{"name":"CPSS Transactions on Power Electronics and Applications","volume":"10 2","pages":"162-174"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10970394","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557716","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}
