The multilevel converters allow us to work at the voltage levels mentioned and give us a low harmonic content in the AC side of the system. However, these power conversion systems consist in their topology of an input transformer, which is sensitive to low order harmonic currents, generating saturation and increased losses. This work proposes a modulation scheme called Feedback Quantizer, applied to multi-cell active front-end rectifiers, aiming to obtain a focused mitigation of low-frequency current harmonics of the power cell. Furthermore, to ensure the stability of the DC voltage of each power cell, a control strategy consisting of nonlinear control, a first-order filter to the DC voltage reference, and a PI control will ensure stability and zero steady-state error at step input. The simulated results show the correct operation of the proposed scheme.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125494561","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}

Initially, a data set of 30,000 constellation images of the QPSK, 16-QAM, and 64-QAM modulations with different identified MER values in dB was generated. These data sets are used to train and validate a convolutional neural network based on the transfer learning in AlexNet network architecture, destined to recognize different types of images. The validation results and a test set obtained from the same database were highly satisfactory. Most of them approach 100% accuracy in the classification, which showed a good detection of modulation and especially discrimination of the MER value when evaluating constellations. ISDB-T signals transmitted by broadcast in the city of Quito-Ecuador and by the laboratory were also evaluated. A professional ISDB-T analyzer and a receiver designed with software-defined radio (SDR) ADALM-PLUTO were used for reception. The results in the receiving equipment show an accuracy of 100% of the detected modulation and very close values between the measured MER values and those obtained by the neural network.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126404032","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 exponential growth of traffic that circulates through the network, together with the changing demand for bandwidth, types of traffic, and the need for rapid deployment of new services, have put into focus the traditional mechanisms in which device configurations are performed manually and statically. Consequently, there is a need to change the design and administration mechanisms to give the network greater dynamism and intelligence. Software Defined Networks (SDN) and Network Automation emerge as revolutionary new network technologies, which promise to provide concrete solutions to these demands. This work tries to relate the needs of traditional networks with what SDN provides, for the analysis of performance and new management capabilities. A simulated laboratory is presented, that allowed different scenarios. For this, different tools for simulation and virtualization were used, such as GNS3, Mininet and ONOS (Open Network Operating System). Within GNS3, topologies were created with Mininet version 2.2.2, connected to the SDN ONOS controller for the required cases. Among some tests, it was possible to determine the shortest convergence time before the fall of links or switchs, for SDN networks compared to traditional networks. The numerical results can be useful for simulation analysts, and network planners and administrators.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125208383","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 using affective intelligent agents within an artificial environment, seven different scenarios were defined. To offer a broader view, three profiles of passenger agents were considered in each of the seven previously mentioned scenarios: Student profile, which assesses the cost of the route over other decision criteria; Worker profile, which values the time of the route over other factors; and Tourist profile, which values the well-being derived from the route over other factors. Well-being is understood as the satisfaction perceived by the passenger derived from the transport service. Likewise, the transit through streets with positive or negative memories has a direct effect on the well-being of the passenger agent. Depending on the scenario and the configuration of parameters, the results show that in some cases obtaining higher well-being does not imply a substantially higher cost. Likewise, in some cases, following an option that seeks higher well-being does not substantially represent a longer travel time.","PeriodicalId":340976,"journal":{"name":"2021 IEEE CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131515739","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}
