Fixed-width multiplier is employed in many digital signal processing applications, as most of these systems employ iterative structures with fixed precision. The design has been implemented in TSMC 180nm technology. The design is 14.6% faster than the fixed-width multipliers. The design has 37.2% less truncation error as compared to direct truncated fixed width multiplier (DTFM). The design is embedded with operand isolator technique to ensure low power operation when employed in DSP applications.","PeriodicalId":151739,"journal":{"name":"2014 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127791413","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 entire setup consists of a full bridge converter which utilised proposed phase shift technique and voltage doubler on the output side. The converter operated at 20kHz switching frequency which is high enough to improve the efficiency. Ferrite core transformer is used in place of ordinary air core transformer. Which is small in size with number of turns of the transformer is reduced and the overall power density is increased. The proposed doubler circuit consists of electrolytic capacitors, which are rated at 400V. This circuit results in cost savings of more than 50% in the price of the electrolytic filter capacitors. The circuits were simulated using PSIM software for an input voltage of 200V, an output of 800V obtained. And it is validated with the low power hardware model.","PeriodicalId":151739,"journal":{"name":"2014 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124605270","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 aims at providing solution for power demand and energy management by using HB white LED lights for domestic applications. LED lights consume very less power and gives out high energy in the form of brightness. A laboratory model is created in DIALUX 4.11 using CAD window and is illuminated with LED lights. Photometric measurements and energy evaluation are done for the laboratory model with room components of different construction materials in the presence of LED lighting. Reflectivity of different materials under illumination is determined. Simulation is done for varying brightness and calculated results are carried over to Pov-Ray 3.6 for determining the real lighting appearance of the laboratory model. Energy evaluation is done for a year and photometric values of lighting system are measured. The calculated results proves that LED lighting system can be used as an efficient lighting system for domestic purposes when compared to other lighting systems. Simulated results and photometric values of LED lighting are presented here.","PeriodicalId":151739,"journal":{"name":"2014 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"435 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126471396","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 these topologies are suffering from leakage currents and they can be reduced by clamping the neutral point during freewheeling modes. Two types of basic switching cells are introduced to build the proposed topology. They are positive neutral point clamping cell and negative neutral point clamping cell. Using these two cells proposed topology is clearly explained. In this paper unipolar sinusoidal pulse width modulation (UPSPWM) which is already existing and modified unipolar sinusoidal pulse width modulation (MUPSPWM) which is proposed to these topologies for getting an improved result. These two types used for creating switching pulse pattern for all topologies and then obtained results are compared in respect of THD. Existing topologies like OH5 and full bridge dc bypass (FB-DCBP) are also simulated with both PWM techniques and their results are compared to proposed topology in respect of total harmonic distortion (T.H.D) and number of switches. Results showing in this paper are validated by simulating with MATLAB.","PeriodicalId":151739,"journal":{"name":"2014 International Conference on Advances in Electrical Engineering (ICAEE)","volume":"750 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122970016","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 hardware is designed to accept data in IEEE COMTRADE format. Different power system operating conditions are simulated in MiPower software package and injected to the relay using National Instrument's NI 9263 converter modules and LabVIEW software package.
