To achieve high power density, it is desirable to reduce the total flying capacitance in this topology. However, for sufficiently small flying capacitances, a discontinuous capacitor voltage mode (DCVM) manifests, leading to an imbalance in inductor currents. This work provides a detailed derivation of the relationship between the critical capacitance describing the onset of DCVM and converter operating parameters. Moreover, the inductor current imbalance is characterized through the development of a clamped steady-state model. To recover balancing when flying capacitance below the critical value is used, a technique to drive the branches with modified duty cycles in a constant power regime is proposed. Experimental validation of the steady-state model and recovery of inductor current balancing are demonstrated on a 4-branch SCB prototype.","PeriodicalId":55233,"journal":{"name":"Compel-The International Journal for Computation and Mathematics in Electrical and Electronic Engineering","volume":"12 1","pages":"1-6"},"PeriodicalIF":0.7,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89388740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parameter uncertainty reduces this accuracy and degrades the controller’s performance. This paper presents a vector control of PMSMs which utilizes a combination of the flux estimation based on current and voltage models of PMSMs via a weighting factor to ensure the best performance at all speeds for excitation at dominant frequencies. The weighting factor can be chosen so that the controller can effectively act as a flux regulator or a current regulator. Furthermore, this paper introduces a framework to formulate the system dynamics suitable for robust analysis and determine the Worst Case Gain (WCG) of the reference tracking transfer function of the closed loop system. The weighting factor is optimized in order to minimize the WCG in presence of parameter uncertainty for inductances and resistance. Using this analysis, the proposed regulator can benefit from the optimal blending of the two flux estimation methods and is robust to parameter uncertainty compared to conventional current and flux regulators.","PeriodicalId":55233,"journal":{"name":"Compel-The International Journal for Computation and Mathematics in Electrical and Electronic Engineering","volume":"26 1","pages":"1-8"},"PeriodicalIF":0.7,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88601159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better resolve the issues caused by excess wind power during a grid fault, a modular DC chopper, containing hundreds of submodules, has been proposed to absorb the excess power in the VSC-HVDC system. The real-time HIL test bench is an efficient way to validate the DC chopper and its controllers. However, conventional electromagnetic transient (EMT) simulation tools have difficulties modeling the choppers of hundreds of submodules for real-time simulation. In this paper, a high-fidelity real-time model of the modular DC chopper is developed and implemented in FPGA and tested by using a real-time simulator. The modular chopper model is implemented in the field programmable gate array (FPGA) with sub-microsecond time resolution, and its small form-factor pluggable (SFP) IOs allow connection to external controllers through optical fibers and exchanging hundreds of signals in a few microseconds. The model is developed with flexibility allowing easy model scale expansion and capability of controller hardware-in-the-loop (C-HIL) testing. The DC chopper model is validated in real-time simulation along with an HVDC system and the real-time HIL test results are provided.","PeriodicalId":55233,"journal":{"name":"Compel-The International Journal for Computation and Mathematics in Electrical and Electronic Engineering","volume":"1 1","pages":"1-7"},"PeriodicalIF":0.7,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79797988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, partial shading can significantly limit PV power production even in stationary installations, and this is expected to be more severe in vehicles. Differential power processing (DPP) approaches can maximize PV output power despite partial shading. This work presents a PV-to-isolated-bus DPP architecture specifically for electric vehicle integration and a converter module that is designed to be extensible and inexpensive. The proposed architecture uses the vehicle’s existing low voltage battery as the common bus for the DPP modules and reuses the existing onboard charger to interface the solar string to the high-voltage battery. The proposed converter module achieves maximum power point tracking (MPPT) for the cell(s) it is connected to without requiring any communication or power transfer across the isolation barrier while allowing bidirectional power with synchronous rectification. The proposed architecture offers an inexpensive solution with high system efficiency and simple control that scales easily to large numbers of DPP units. The paper will include modeling of the advantages of the architecture, experimental characterization of the proposed DPP module, and experimental demonstration in a multi-cell, multi-DPP system.","PeriodicalId":55233,"journal":{"name":"Compel-The International Journal for Computation and Mathematics in Electrical and Electronic Engineering","volume":"20 1","pages":"1-7"},"PeriodicalIF":0.7,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72785653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
