Thus, migration to induction cookers replacing gas stoves is driven by the state through efficient cooking program. In this context, the study of the problems that the use of induction cookers will bring to the grid, when its use massively is evident. This work focuses on the generation of harmonic induction cookers due to switching the inverter. That said, two modulation techniques are analyzed in this paper, modified SPWM and trapezoidal modulation. To this, it was simulated in simulink/matlab both modulations controlling an inverter series resonant full bridge feeds the induction cooker. Product of these simulations the harmonics in the voltage signals obtained is calculated and analyzed. As a result it is concluded that by the modified SPWM modulation a voltage signal with lower levels of harmonics is obtained, which would facilitate filtering signals and the effect of harmonics on the network would be smaller.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123003219","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}

Lately, there has been considerable interest in GP's community to develop semantic genetic operators, i.e., operators that work on the phenotype. In this contribution, we describe EvoDAG (Evolving Directed Acyclic Graph) which is a Python library that implements a steady-state semantic Genetic Programming with tournament selection using an extension of our previous crossover operators based on orthogonal projections in the phenotype space. To show the effectiveness of EvoDAG, it is compared against state-of-the-art classifiers on different benchmark problems, experimental results indicate that EvoDAG is very competitive.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"166 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116058269","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 paper presents the simulation analysis of different commutations' scenarios in the IPS to identify current and voltage characteristics in sources and loads. In addition, the use of optocouplers synchronized with the power grid and a dead-time, is proposed in order to enable a correct control of commutations between ports. Experimental results show that the proposed solution allows that commutations in the IPS have been performed properly to avoid short-circuit current in the system. Likewise, it is evident that the use of a dead-time between commutations is very important to avoid possible faults or connection mistakes between ports, it which may occur due to the phase difference between the power sources or the loads power factor.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116645959","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 work's incremental contributions are: First, a small and simple regulated cascode current mirror (RGC) is presented that is composed of a common source amplifier coupled with a diode connected self-cascode (SC). This RGC is incorporated in a standard folded cascode amplifier to boost its gain and modestly increase its high impedance output's operating head room, which is beneficial in the sub 1V power supply (VDD) environments. Second, amplifier's inputs can span to the rails via using two pairs of differential PMOSFETs in parallel, where the secondary pair is DC level shifted by NMOSFETs. As the amplifier's inputs span the rails, a single FET steers the same tail current between the amplifier's primary and secondary input PMOSFET pairs, thereby keeping its transconductance almost constant, considering that the amplifier operates in subthreshold. Montecarlo (MC) and worst case (WC) simulations indicate the following specifications are achievable: VDD minimum ∼ 0.8v; IDD ∼ 260nA; input range rail to rail; offset voltage ∼ 5mV; output range ∼ 25mV from the rails; open loop gain (Av) ∼ 138dB with unity gain bandwidth (fu) ∼ 2MHz and phase margin (PM) ∼ 30 degrees; power supply rejection ratio (PSRR) ∼ −120dB; common mode rejection ratio (CMRR) ∼ −140dB; slew rate (SR) ∼ 1V/ uS; settling time (ts) ∼ 3uS.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121381381","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, controllers are often designed without considering the dynamic behavior of the actuators; situation that leads to excessive controller actuation and diminishes the overall performance of the aircraft, including its energy consumption. In this paper, we discuss the dynamic effects of the airflow induced by a propeller, in hover mode, on the thrust produced, the dynamic response of the actuators, and we determine a thrust correction factor for the effective thrust as well as a bandwidth of the dynamic response, which can be used as designing parameters to improve the controller design. Using a mechanical analogy, we show the implicit assumption on the inertial frame of reference when the Conservation of Momentum Theory is used to calculate the thrust in a hovering propeller; assumption that modifies the perception of the produced thrust with respect to the effective thrust observed in an absolute frame of reference. This highlights the importance of the horizontal change of momentum of the incoming airflow, neglected in traditional approaches but responsible of the effective force of lift in the steady state of the propeller when an ideal fluid is assumed. Finally, we introduce a simple dynamic model of the airflow induced by the propeller and provide an estimation of the maximum bandwidth response to be expected from the actuators.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123203811","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 this work, a methodology based on adaptive filter using the least mean squares algorithm for tracking of voltage variations and a fuzzy logic system for automatic classification are proposed. The proposal consists of three stages: 1) denoising through a lowpass filter to remove non-fundamental frequency components, 2) envelope and type of voltage tracking, and 3) final classification according to the IEEE Std. 1159 using a rule-based decision process. In order to validate and test the proposal, a set of synthetic and real signals is used. The obtained results demonstrate the proposal effectiveness to detect and classify voltage variations, even when they are embedded in high level noise. Unlike other reported works, the proposed fuzzy logic system allows the tracking of the voltage variation such as sag, swell, or interruption over time, it means sample to sample.","PeriodicalId":166098,"journal":{"name":"2016 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125417304","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}
