Battery energy storage systems (BESS) allow not only to match consumption and generation profiles more closely, but also they provide various ancillary grid-supporting services. The enabling technology for these emerging opportunities is related to power electronic interfaces between the DC battery and the AC grid. Generally, a two-stage power conversion approach is used, where the battery-side DC-DC stage is responsible for controlling the battery current and grid-side DC-AC stage controls the current taken or injected to the grid. These two stages are connected through a bulky DC-link capacitor with stabilized voltage. Such an approach has however reached its limits in terms of efficiency, power density and cost. Therefore, a lot of research is currently focused on alternative topologies, enabling higher performances than the well-developed two stages approach. One of the promising configurations of such alternative topology includes a DC-DC converter, that forms sine voltage half-waves and an unfolding circuit, which provides the commutation of these half-waves to the grid. This paper presents a review of unfolding converters in the context of BESS. Configurations of unfolding circuits with DC-DC choppers, dual active bridge converters and multilevel converters, as well as the partial power converters are analyzed.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114081950","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 operating conditions of these inverters vary across a wide range, leading to different small-signal impedances and different grid-interface behaviors. Analytical impedance models derived at specific operating points can hardly capture nonlinearities and nonidealities of the physical systems. The applicability of electromagnetic transient (EMT) simulations is often limited by the system complexity and the available computational resources. This paper applies neural network and transfer learning to impedance modeling of grid-tied inverters. It is shown that a neural network (NN) trained by data automatically acquired from EMT simulations outperforms the one trained by traditional analytical models when unknown information exist in simulations. Pre-training the NN with analytically calculated data can greatly reduce the amount of simulation data needed to achieve good modeling results.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"197 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123107042","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}

This is mainly because of its excellent characteristics in terms of voltage/current stress profile of the switches, bidirectional power flow capability, and efficient operation. Nonetheless, due to its half-dc link voltage utilization in the ac output voltage, another power processing stage with additional active and passive elements is required to make its output voltage compatible with the grid when low and wide varying input dc source is available. In this paper, a novel ANPC-based five-level (ANPC5L) inverter with a single-stage boost-integrated circuit design is presented. The proposed topology is able to make the peak output voltage of the conventional ANPC5L inverter followed by a front-end bidirectional boost converter double using the same number of power switches but with less total standing voltage across semiconductors. The working principles of the proposed topology is discussed. Experimental results obtained from 1.3 kW laboratory-built prototype under the grid-connected condition are also given to support the discussion.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127838368","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}

By connecting an external capacitance Cext in parallel with the drain and source of SiC MOSFET, the soft turn-off switching of SiC MOSFET can be achieved. However, the impact of Cext on the turn-on switching process of SiC MOSFET is unclear. In this paper, an analytical model based on a half-bridge configuration is established to study the turn-on switching characteristics of SiC MOSFET. The nonlinearity of parasitic capacitances, transfer characteristic, and output characteristics are considered in the model to ensure accuracy. Besides, the reverse recovery characteristics of the body diode as a freewheeling diode are measured experimentally. Based on the model, the effect of Cext on the turn-on switching characteristics of SiC MOSFET is deeply analyzed. Finally, an experimental platform is built to verify the model.","PeriodicalId":276307,"journal":{"name":"2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132262650","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}
