Apart from data acquisition and pre-processing, the other essential component of using acoustics is to design an analysis methodology, that can culminate in practical applications. This paper applies Gaussian Mixture Models and Self-Organising Maps to cluster pre-processed AE hits obtained from acoustic sensors in the form of tensile, shear and mixed modes of compression on a material. For an in-depth analysis, custom features such as high peak regions, low peak regions, strongly hit and weakly hit signals are introduced to compare with the clusters formed. The results show that for small AE signals that are obtained or extracted after events detection, a time-domain based clustering can be applied and used for isolating similarities and distinctions among the signals belonging to the same group.","PeriodicalId":443337,"journal":{"name":"IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121800524","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 transfer maximum energy in a short time, the process of detecting an approaching vehicle and transmitting power must be carried out quickly. In most of the previous studies, problems of vehicle detection and power transmission have been considered separately. In this paper, the power transmission control process is proposed that combines vehicle detection and current control. The detection process uses only vehicle-side voltage pulse which enables both road-side and vehicle-side coils to sense approaching of the vehicle-side coil. And the current control suppresses the current overshoot at the start of power transmission. The proposed method was verified by experiments. Both coils could detect another one at a sufficient distance from each other. Additionally, power transmission starts at a point of small coupling coefficient was achieved without current overshoot.","PeriodicalId":443337,"journal":{"name":"IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116657783","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}

Therefore, the driving signals of MOSFETs at the secondary side of the converter for synchronous rectification can be modulated to reduce the circuit conduction loss. To solve this issue, in this paper, a synchronous rectification method based on regulating phase and duty cycle of the secondary side MOSFETs driving signals in bidirectional CLLC resonant converter is proposed to reduce the conduction loss. According to the relationship between the switching frequency and the first resonant frequency, the driving signals of synchronous rectifier can be achieved.

Via a numerical example, we highlight that the conventional tuning method of the voltage and current loops may not ensure system stability. This is because the tuning method does not consider full-order system dynamics. Thus, we improve the tuning method for the VSM voltage and current loops using small-signal analysis of the full-order VSM model. The proposed tuning method ensures system stability in the small-signal sense, and it is computationally inexpensive. We verify the effectiveness of the proposed tuning method via numerical simulations.","PeriodicalId":443337,"journal":{"name":"IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society","volume":"725 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116982168","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 equivalent circuit parameters are minimally affected if the winding consists of a high number of parallel wires, and only a single turn of one parallel wire is short-circuited.

To fulfill requirements such as ancillary grid services, the virtual synchronous machine has been in the focus of research as grid-supporting or grid-forming control for grid-connected power electronic converters. Its application in WEC requires an adaption of the overall control structure compared to a conventional vector control, so that also the widely investigated active damping controls for mechanical torsional oscillations need to be analyzed for the adapted structure with a machine-side DC-voltage control. Therefore, in this paper methods to achieve active damping of torsional oscillations are designed with extended DC-voltage control. A special regard is put on the non-linearity of the intermediate circuit and the variable stator voltages of variable-speed WECs. Simulation results validate the effectiveness of the active damping controls and the stability of DC-link voltage control.","PeriodicalId":443337,"journal":{"name":"IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121310732","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 case of DC faults (pole-to-pole and pole-to-ground fault), the high fault current flowing through MMC arms may damage the devices present in the MMC. Among the AC faults, the valve side single phase to ground (SPG) fault in HB-MMC based asymmetrical monopolar and bipolar HVDC system is one of the most serious faults. It produces some special characteristics like non-zero crossing of the grid side currents which prevent the AC Circuit breakers (ACCBs) present in the grid side from operating; further, capacitor overvoltage happens in upper arm submodules. In this paper, a Fault Limiting Circuit (FLC) is proposed to solve the above problems. The proposed circuit acts as a parallel LC resonant circuit formed by inserting a capacitor in parallel to arm inductor during fault condition which provides high impedance to the fault current path and reduces the fault current. This circuit is activated during fault condition only, hence the efficiency of the converter is not compromised. The operation of the FLC with HB-MMC is analyzed and verified by simulation in EMTP platform, showing a good agreement between simulation results and theoretical analysis.","PeriodicalId":443337,"journal":{"name":"IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124774805","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}
