The advancement in technology could make the communication system faster, better and reliable. Microwave design is quite helpful in taking those challenges to provide such requirements. It is possible to develop components, where size, performance and cost can be adequately minimized. In this paper we propose a micro strip line low pass, band pass filter for ISM band and Ku (8-12GHz) band for satellite communication etc. that comes under microwave range. In this work we also addressed a hair pin filter centered around 1.5 GHz provides a bandwidth of 1000 MHz. This result could be instrumental for many unlicensed band applications.

In order to eliminate the harmonics, the switching angles are obtained by solving the non-linear transcendental equations using Newton-Raphson method. However, in the proposed online Artificial Neural Network (ANN) method, the firing angles are calculated by Bayesian Regularization Back- propagation learning algorithm where look up table is not necessary to store the firing angles. Further, with the help of the obtained switching instants, PWM signals are generated and applied to the single phase inverter in MATLAB Simulink. The output waveforms of inverter with R load for various values of modulation index are analyzed. Furthermore, the performances of different ANNs were compared with the gradient descent algorithm.","PeriodicalId":222759,"journal":{"name":"2018 International Conference on Applied Electromagnetics, Signal Processing and Communication (AESPC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131944043","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 main aim is to optimize money and satisfy load balance and certain limits which will serve some change in load and constraints.

The constriction factor as proposed in earlier works is very useful for the convergence of the PSO algorithm. This factor is varied in this work and an improved result is observed. Two case studies are carried out on 10-unit and 20-unit system for the verification of viability and execution of the suggested approach. The suggested approach is implemented for an hourly dynamic and static load using MATLAB.
