The proposed converter achieves a higher demagnetization voltage with a much lower voltage rating of the energy recovery capacitor, as compared to other energy recovery-based converter variants. Furthermore, the voltage ratings of the active switches in the proposed converter are lesser than that of the conventional converters, for a given demagnetization voltage. The availability of soft-chopping operation in the proposed converter is beneficial for reducing the high-frequency ripple in the torque and lateral vibration of stator poles. This article presents the converter topology, its operating modes, and the design of the energy recovery stage in detail. Experimental results are presented to show the drive operation of an 8/6 switched reluctance motor driven by the proposed converter. A detailed comparison of the proposed converter with the conventional counterparts is also presented.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"135-145"},"PeriodicalIF":0.0,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed model puts forward an alternate analytical method to consider the magnetic nonlinearities of all the motor segments. The formulation employed to develop the model attempts the implications of saturation and magnetic nonlinearities to incorporate them in the form of geometry modulation. The implementation does not correspond to any domain extension or magnetic vector-potential dependent term and, hence, does not endure the rank deficiency with infinitely permeable iron. The estimation accuracy of the model is demonstrated by evaluating the performance of a four-pole medium-scale laboratory prototype of a squirrel cage induction motor for a wide range of magnetic loading. Comparing the results obtained with the proposed method, finite element analysis, and measurements, it is observed that the proposed formulation enables the subdomain to achieve reasonable accuracy.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"146-156"},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet the wide voltage range of distributed energy resource, the converter operates as a versatile circuit with buck, transition, and boost modes. At the boundary between buck and transition mode, the parasitic resistance will introduce voltage overshoot. In contrary, at the boundary between transition and boost mode, the parasitic resistance will lead to oscillation and instability. To solve the problem, the additional voltage overlap is artificially introduced to compensate the parasitic resistance. The expense of voltage overlap has been analyzed considering current stress and voltage overshoot. To suppress the voltage overshoot during mode switching, control compensation is proposed in the voltage control loop. The influence of parasitic resistance and the proposed compensation method has been tested through comparative simulations and experimental results, in verification of stable voltage regulation under wide output voltage range.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"777-789"},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Model predictive control (MPC) is an advanced control technique gaining popularity in power electronics applications, particularly in EV chargers. MPC uses the plant's mathematical model to predict the future behavior of the state variables. Predictive repetitive control (PRC) combines MPC and repetitive control to increase robustness against disturbances, such as parametric errors or significant perturbations in grid voltage. This article proposes a robust PRC direct power control (PRC-DPC) of an EV charger grid-side converter operating under disturbed conditions. An explicit stability and robustness analysis is provided using the robust margins derived from the structured singular value decomposition (SVD). The analyses highlight the impact of the PRC-DPC controller tuning on its robustness. Experimental tests were conducted on a 2 kW prototype EV charger in V2G operation mode to validate the robustness of the proposed PRC-DPC controller. The proposed controller presented superior robustness compared to the conventional MPC.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"594-602"},"PeriodicalIF":0.0,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, a discontinuous pulsewidth modulation (DPWM) strategy with improved input currents for an active third-harmonic injection indirect matrix converter (3HI2MC) is presented. The proposed DPWM modulation strategy not only preserves the inherent advantages of the 3HI2MC, maintaining independent modulation and control of the rectifier and multiple inverters, but more importantly, the narrow pulsewidth problem existing in the conventional indirect matrix converter (IMC) is avoided and the input current ripple is reduced dramatically. The above features make the 3HI2MC with the proposed DPWM strategy competitive for the applications that require multiple drives and high-quality input currents. Besides, to obtain the third-harmonic injection current reference, an input current reconstruction method utilizing the output parameters of the inverters without extra current sensors is developed. After describing the topology structure, operating principles, modulation strategy, and control algorithm in details, the experimental results are presented to demonstrate the validity and effectiveness of the proposed modulation strategy.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"157-164"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To deal with the challenge, a delay-free decoupling method is proposed in this article. The method reduces both the dimension of matrix multiplication and the number of switch state combinations without sacrificing numerical stability and compresses the calculation progress by representing the decoupled system with the discrete state-space equation. The PE system is decoupled at the series/parallel interface of submodules, treating currents as boundary variables linked to each submodule's extended port. A preliminary formula for these variables is derived by simultaneously solving nodal voltage equations and kirchhoff voltage laws (KVL) equations. Submodule solutions are compacted and parallelized based on the discrete state-space equations. These equations are then substituted back and decomposing boundary variables into independent segments, to achieve parallelization of boundary variable solutions. The proposed method is validated through real-time simulation of cascaded PE systems on an field programmable gate array (FPGA) platform with a 250 ns time step. Results show that it achieves high precision compared to nondecoupled systems in power systems computer aided design (PSCAD) across diverse transient conditions. Additionally, it boosts the simulation scale by roughly 2–7 times on the FPGA-based platform compared to nondecoupled nodal analysis.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"391-402"},"PeriodicalIF":0.0,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
