The dc capacitor voltage is controlled by fuzzy logic controller. The diode rectifier feed RL load is taken as a nonlinear load. Comparisons made between the use of Self Tuning Filter based extraction technique of the 3 level inverter with that of classical extraction technique with Delta Modulation. The self tuning filter allows extracting directly the voltage and current fundamental components in the axis without phase locked loop (PLL) under distorted voltage condition. The comparative analysis is made based on working under distorted voltage condition, and the total harmonic distortion of source current after compensation. Self tuning filter based extraction technique is good under distorted voltage conditions. The total harmonic distortion (THD) of source current is fully reduced and inverter switching is 3–4 times fast in delta modulation based active filter, but it produces poor result under distorted voltage condition. The effectiveness of the two methods is theoretically studied and verified by computer simulation.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"13 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":"124764491","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 paper investigates the self tuning control scheme for SMES is proposed and applied to Automatic Generation Control (AGC) in power system. The system is assumed to be consisting of two areas. The proposed self-tuning control scheme is used to implement the automatic generation control for load frequency control application adding to conventional control configuration. The effects of the self tuning configuration with Fuzzy Proportional Integral Controller (FPIC) in AGC on SMES control for the improvement of Load Frequency Control (LFC) is compared with that of PI controlled AGC. The effectiveness of the SMES control technique is investigated when Area Control Error (ACE) is used as the control input to SMES. The computer simulation of the two-area interconnected power system shows that the self tuning FPIC control scheme of AGC is very effective in damping out of the oscillations caused by load disturbances in one or both of the areas and it is also seen that the FPIC controlled SMES performs primary frequency control more effectively compared to PI controlled SMES in AGC control","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"1 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":"131277799","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}

One recent promising renewable energy power source is the Piezo-electric Generator (PZG) that extracts energy from mechanical vibrations. Due to low power and wide-range ac output voltage, the Piezo-electric Generator cannot directly support the ac or dc electrical appliances. Hence in most applications, the ac signal produced by this generator needs to be rectified. This paper focuses on the selection of higher efficiency rectifier for increasing the available output power of Piezo-electric Generators that have a high output capacitance. This proposed analysis deals with comparing the efficiency of Diode bridge rectifier, SEPIC rectifier and Resonant rectifier by conducting the simulation studies using PSIM software package. From the simulation results, the rectifier which provides the maximum efficiency is identified and is proposed for energy harvesting applications.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"1 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":"130321074","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 aim of the work is to reduce the cost and size of a brushless dc motor (BLDC) drives as well as increase the reliability and ruggedness of that drive. Traditional BLDC drives use Voltage Source Inverter (VSI) that utilize hard switching, thereby generating switching losses and entail the use of large heat sinks. VSI needs a huge dc link capacitor that is inherently unreliable and is one the most expensive components of drive. Hence, a Current Source Inverter (CSI) is used to replace the hard switching by soft switching, thereby eliminating the heat sinks as well as the large dc link capacitor. A controlled rectifier together with a large inductor act as the current source, the only disadvantage is the large value of the dc link inductor and the huge number of turns needed to achieve these values of the inductances lead to huge resistive losses. Therefore, it is shown that it is possible to replace the controller rectifier and the large inductor with a suitable Buck converter based current source inverter switching at high frequencies and much smaller value of the dc link inductor without increasing the current ripples. Hence, it is possible to have the advantage of using a CSI as well as reduce the value of the dc link inductor without a corresponding increase in the heat sink. The effectiveness of the VSI and CSI fed BLDC motor schemes are verified through the simulation results.","PeriodicalId":305797,"journal":{"name":"2011 INTERNATIONAL CONFERENCE ON RECENT ADVANCEMENTS IN ELECTRICAL, ELECTRONICS AND CONTROL ENGINEERING","volume":"106 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":"133354323","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}
