The investigation is motivated by the rise of Unbalanced Magnetic Force (UMF) resulted by asymmetric disposition of phase windings. It can be seen that a significant reduction of UMF is possibly achieved by employing uneven number of turns per coil. However, a slight reduction of torque performance exists which could be due to higher saturation on stator magnetic path at rated condition. It is also shown that the significant reduction of UMF is mainly due to the reduction of radial force density component while the tangential force density component remains unchanged.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128759801","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}

Optimal sizing of components can reduce the cost of hybrid systems. This article illustrates the size optimization of solar-wind-diesel generator-battery hybrid system designed for a remote location mobile telecom base transceiver station in Nigeria. Different energy combinations have been analyzed using HOMER 2.81 (Hybrid Optimization Model for Electric Renewables) in order to determine an optimal model. Simulation results show that the hybrid energy systems can minimize the power generation cost significantly and can decrease CO2 emissions as compared to the traditional diesel generator only.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116671501","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}

Minimizing harmonic distortion is a challenging issue for power electronic drive. This problem can be solved by developing suitable modulation technique. There are number of modulation techniques established in the last decade. Among them, the space vector pulse width modulation (SVPWM) is extensively used because of their easier digital realization, better DC bus utilization and lower THD. Conventional SVPWM requires different number of logical computations of on time calculations and different number of lookup table for each triangle due to having their different number of switching states. In this paper, a simple SVPWM is presented where proposed only four logical computations of on time calculation, four active switching states and four lookup table for each triangle. Five level cascaded h-bridge inverter (CHBI) based on SVPWM technique are modeled and analyzed by using MATLAB/Simulink and origin 6.1 with a passive R-L load that can be extended to any level. These results are compared with other lower levels of inverter and with previous established results. From these results, five level CHBI based on SVPWM shows better performance compared to others in terms of THD.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123491711","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 order to use electrical energy efficiently, the technical development of power electronics - or power conversion technology - is urgently needed[2]. In response to this need, our aim is to nurture power electronics engineers. To this end, we have constructed an education system that presents the complete picture to students from the basic structure of power devices through to their application circuits. By performing simulations using TCAD (Technology Computer Aided Design), this education can be provided at low cost because there is no need to create actual functioning devices. The proposed system deepens the understanding of students by clearly showing them the internal structure and impurity concentrations of power devices, something that is difficult to illustrate using real devices. In addition, the system also deepens understanding of circuits by having students design and create circuits using power devices and then having them consider the resultant waveforms.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"709 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123839542","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 purpose of the control strategy is to increase the capability of regenerative braking energy capturing and to improve DC bus voltage regulation. The control strategy uses cascade voltage and current control of SCs. The voltage and current references are calculated based on the speed command and acceleration including the power losses of the system. The whole electrical drive system is mathematically modelled and the core features of the control strategy are presented. Numerical simulation demonstrates the benefits of the proposed control strategy in term of energy saving and DC bus voltage regulation improvement compared to the BEV without SCs.","PeriodicalId":342510,"journal":{"name":"2014 IEEE Conference on Energy Conversion (CENCON)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116038144","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 order to have ideal output, a PID controller is implemented such that the output voltage is regulated on the predefined value.
