Resonant DC-DC converters are increasingly used in applications that require high-power density and high-efficiency. At the same time, a control system for the series-resonant converter is introduced in order to reduce the switching power losses. The main advantage of resonant converters is their soft-switching which solves the problem of high-frequency operation. The resonant load topology is also studied and applied. In this way, zero-voltage switching (ZVS) is achieved in the H-bridge converter. This control algorithm aims to achieve its optimum operating point. In this case, the operating frequency in the resonant converter can vary over a wide range during the melting cycle in the induction furnace. The resonant converter has variable frequency control and phase-shift modulation so that the LLC resonant tank can operate at the resonance point in the load. Matlab-Simulink has been the software used to develop the high-power resonant converter, as well as to support the previous analysis. The simulation results obtained are shown in the paper.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128209343","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}

Identification of two-phase flow patterns is a complicated task due to the diversity of factors on which these flow patterns depend. The performance of the process of training, validation, and classification tests of images of two-phase flow patterns using convolutional neural networks is presented. In order to carry out this procedure, series of frames were extracted from experimental videos. Afterwards, an image catalog with samples of representative flow patterns with the types of slug, annular, semi-annular, and dispersed annular flow was defined, in addition a category of superior annular was included, described by presenting the annular flow pattern in the upper section while the appearance of disturbances at the bottom of the image, this last category represents a transition process between the annular flow and another flow pattern. The pattern identification effectiveness obtained with the proposed scheme was greater than 90%, for the five flow patterns used, demonstrating that convolutional neural networks can perform two-phase flow regimes identification.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"06 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127201470","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 behavior has been explained as the result of unmodelled dynamics in imperfect switching without regarding the intrinsic dynamics excited by a finite time transition in discontinuous control. In this paper, in order to provide a better understanding of the dynamics involved in the switching control, the author presents a model of fast switching transitions introducing the neglected dynamics of a almost instantaneous change, and analyses its effects on the natural dynamics of the plant using, as generic case of study, a second order linear plant. The analysis first recalls some basics differential equations concerning their general solution as the addition of both, the forced solution induced by the control input, and the homogeneous one of the free dynamics of the plant; then, introduces a switching model of the fast dynamic changes of a almost instantaneous transition to determine the excited free dynamic response, considering a second order linear system as a plant. Finally, discusses about its effects into the general dynamics of the plant inducing the oscillatory behavior observed in the state variables.","PeriodicalId":174166,"journal":{"name":"2021 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128405012","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}
