Seven different designs were investigated in small signal measurements and 3D-FEM-simulations. The results were proven by calculated results of equivalent diagram circuits, which have been developed. Regarding the standard crosswise current arrangement all designs show the same results. In a horizontal aux. current arrangement, the effect of the VAG technique is mitigated.

For a high number of output voltage levels, nearest-level control is typically used, whereas an optimized waveform can be presumably used to eliminate a selection of low order harmonics. A nonlinear optimization problem for any kind of multilevel inverter, operating in a single or three-phase arrangement, is formulated. It is shown that the set of nonlinear equations, defining this optimization problem, cannot be numerically solved, if the number of output voltage levels is higher than nine. Thus, an optimization algorithm, e.g., Matlab's genetic algorithm, should be used instead. Based on the concept of the weighted THD, it is shown that an optimized waveform has no effect on the output current's quality of a single phase multilevel converter. However, considering an ungrounded three-phase system, the content of the to be eliminated harmonic components is shifted towards the triplen harmonics and, consequently, the expected current quality, based on the WTHD, can be significantly improved.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114817931","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}

High Sensitivity Current Transformer with low Settling Time, for Magnified AC Current Measurements in Pulsed Applications 高灵敏度电流互感器，低沉降时间，用于脉冲应用中的放大交流电流测量

Despite its low amplitude (usually measured in ppm) the ripple current could have a major impact on the performance of the system and therefore needs to be quantified/reduced. However, measuring such currents is challenging, due to the limited resolution of the current probe, especially when the DC offset current of the pulse is in the kA range. Therefore a suitable AC current probe able to perform magnified ripple current measurements with high fidelity is proposed in this paper. The probe is based on the principle of current transformers and filters the DC offset of the pulsed current, enabling to measure the ripple with a very high resolution. The design trade-offs of the conventional CT for such an application are explained, and an adaptive burden resistance topology is proposed in order to achieve simultaneously a low settling time, which is essential for measuring short pulses, and the needed high sensitivity, while maintaining a relatively high bandwidth.","PeriodicalId":241752,"journal":{"name":"2020 22nd European Conference on Power Electronics and Applications (EPE'20 ECCE Europe)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123520362","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}

However, controlling the flow of power in these converters becomes more and more complex as the number of ports increases. Power flow in a multi-port active-bridge converter is controlled through phase shifts and duty cycles. Analytical and Numerical methods, when suitable, often require huge amounts of processing and memory resources for real-time control of the power in converters with three or more ports. This work proposes a method that is computational cost efficient and can be employed for realtime control purposes. It is scalable and can be applied to any number of ports.

Otherwise, minimizing the Levelized Cost Of Energy (LCOE) is the key to have the tradeoff between wind farm cost and the annual energy delivered to the terrestrial network.
