By operating the converters in chaotic mode EMI can be reduced without adding any filters. In this paper, voltage controlled buck converter is analyzed by FFT for EMI reduction under chaotic mode operation is proposed. The chaos is induced externally into the buck converter by using Wien bridge oscillator as its exhibits various forms of chaotic behaviour when operated in oscillatory mode. Simulations are performed using PSpice for observing chaos for the variation of input voltage. EMI reduction is observed for both conventional model of buck converter operating in chaotic mode for certain voltage range and proposed model of buck converter using FFT by spreading the spectra of the output signals over the whole frequency band. A protype model has been tested and hardware results shows the significant reduction of EMI in chaotic mode operation of buck converter.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121153554","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}

For these reasons, DG predicted to play an increasing role into the electric power systems of the near future. In this paper, two types of DGs are considered for implementation and DGs are modelled as PQ bus. The suitable location for placing distributed generation (DG) is identified through loss sensitivity factors and L index. The fuzzy adaptation of evolutionary programming has been chosen as it is particularly suited while solving optimization problems of multiobjectives. This technique is used to find the optimal size of distributed generation (DG). The objective of this paper is to minimize the total payments toward compensating for system losses and DG's capital costs by optimal siting and sizing of two types of DG. This new technique is tested on IEEE-34 bus radial distribution system and the results obtained justify the importance of optimal placement of distributed generation (DG) for minimizing losses and maximizing saving while maintaining appropriate voltage profile at all the buses.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116266855","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}

Power electronics deals with the study and design of Thyristorised power controllers for variety of application like Heat control, Light/Illumination control, Motor control — AC/DC motor drives used in industries, High voltage power supplies, Vehicle propulsion systems, High voltage direct current (HVDC) transmission. Due to these devices harmonics are produced. These harmonics leads to switching loss which affects the performance of the system. So the harmonics should be eliminated from the system. This paper proposes a technique to eliminate pre-specified order of harmonics from the output waveform of AC/AC converters. Selective Harmonic Elimination (SHE) in Pulse-width modulation (PWM) technique can be used for the elimination of harmonics which necessitates solving systems of nonlinear equations. The main challenge involved is to solve these nonlinear equations, which are transcendental in nature and therefore have multiple solutions. Genetic algorithm (GA) technique is introduced to minimize the computational burden associated with the nonlinear transcendental equations of the SHE-PWM method. The proposed algorithm could calculate switching angles efficiently resulting in fast convergence.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124162166","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}
