The combination of these two technologies might answer for electrical and power requirements in different electrical mobility application fields, such as battery charging. Accordingly, due to the low conversion losses the combination of these two technologies can provide, compact, cost effective and highly efficient power converters can be derived, thus potentially answering the scalability requirements for the Electric Vehicles (EV) market. To assess the operation of the proposed circuital solution, a Full Bridge (FB) CPT isolated interfacing converter prototype has been designed and built. Since GaN switches were used for the primary bridge, by taking advantage of their low input capacitance and gate charge, a 500 kHz switching frequency was set, thus deriving a compact power converter. The prototype has been designed for applications up to 12 kW (600 V, 20 A), and tested close to 3 kW (up to 400 V or 15 A) for the purpose of this work to demonstrate its functionality. The measurements assessed a conversion efficiency above 90% with a peak of almost 95%.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128975526","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 method is intended to be used during preliminary study, when STATCOM size and control strategy are not yet defined. To choose the most effective location, performance indices based on the network’s required behaviour need to be defined. The presented method was designed in the frame of a research project named COSTAM, dealing with STATCOM behaviours in a real MV distribution network with massive photovoltaic (PV) production. The proposed method was applied to a real case MV network considering future PV integration scenarios. Network modelling, load/generation scenarios based on 2050 PV integration forecast, performance indices and STATCOM control strategies were defined for this case study, leading to the optimal STATCOM location selection. Method and results applied to this case study are detailed in this article to illustrate the general method. The main advantage of this method is its pragmatic approach. It is easily applicable by Distributed System Operators (DSO) in their network.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"158 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120973735","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}

Transmitting these large high-frequency data sets to the cloud to closely monitor the operational environment and make decisions is not feasible for two reasons: (a) bandwidth and latency issues and (b) higher cost of data transfer and storage. Condition monitoring applications usually extract critical features from raw high frequency sensor signals and discard raw data to mitigate this issue. The computation is carried out on an edge device near to the application hardware and the role of the cloud/remote server is limited to receiving fault types, features, and monitoring. Therefore, this paper proposes an intelligent data capturing methodology with an edge-cloud framework for grid power quality monitoring of the IMAs that only triggers and transmits datasets to the cloud if the raw datasets contain any grid events and/or grid side anomalies. Using dSPACE, grid emulation is carried out virtually. Feature extraction using Short Term Fourier Transform (STFT) is done in the edge device and grid events are detected based on features. The proposed methodology is configured to send raw grid voltage data and features in the Microsoft Azure-based cloud that contain at least one abnormal grid event. Thus, the proposed approach of this paper limits the space requirement in the cloud by 95%, saves data transmission costs, and enables the cloud to run predictive maintenance algorithms.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114259372","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}

It shows a high torque-to-weight ratio and has an excellent utilization rate of the magnet material. In this paper, the geometry of the U-core laminations is investigated in depth. Therefore, the tooth width of the U-core laminations was varied under adjustment of slot width and stator MMF (ampere-turns). The corresponding output torque was simulated for each combination, and the simulation results were verified with the measurement results of the latest prototype. With this investigation, an optimum between the active weight and the torque output can be found. Furthermore, design rules for the U - core geometry in terms of torque smoothness and torque overload capability can be derived.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"194-199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678194","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}

Once the topology of the compensation network and the operating frequency are selected, there are infinite combinations of the circuit equivalent inductance and compensation capacitance values resonating at that frequency. Choosing an appropriate ratio between these passive devices is essential to meet the target output power while ensuring that the required DC input and output voltages are found within the permitted range limited by the power source and the battery load. This paper proposes design trade-offs for selecting the optimum ratio between the inductance and capacitance in IPT systems with series-series compensation applicable to any power level. First, the target mutual inductance must be computed. Based on that, the coupled coils are designed depending on the physical constraints. An example is provided considering a 3.7 kW wireless charging system for electric vehicles (EVs) where different coils’ combinations are analyzed through the finite element method. The most suitable design is implemented, achieving or the application a relatively high measured peak DC-to-DC efficiency of about 96.24% at 3.28kW while the coils are aligned with 11cm distance. The required power is delivered at different battery voltages and coils’ alignments by regulating the DC input voltage.","PeriodicalId":365235,"journal":{"name":"2022 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117009720","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}
