Space vector PWM (SVPWM) has better harmonics performance along with higher rms voltage. Command voltage reference for all the three phases of three phase SVPWM is actuated as a whole. The logic behind this algorithm is that it averages the output vector of the inverter equal to the reference voltage vector. Due to complex nature of its operation, there is a computational delay involved in SVPWM, this often bounds its working up to few kHz of switching frequency. An Artificial Neural Network is used to solve this particular problem in this paper. The computational delay is negligible in case of feedforward neural network especially when a parallel architecture based dedicated application-specific IC (ASIC) chip is used. The conventional back propagation method undergo drawback such as overfitting the network. In this paper an alternate learning algorithm Bayesian Regularization method is used for training of the Neural Network. Bayesian regularized artificial neural networks (BRANNs) does not require cross-validation and are extra robust than conventional back-propagation neural network.","PeriodicalId":308604,"journal":{"name":"2016 3rd International Conference on Electrical Energy Systems (ICEES)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115988680","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 presents an experimental procedure to determine whether a given motor drive would exhibit such oscillations, and if yes, the region of such oscillatory behaviour. In particular, this paper presents case studies on oscillations on account of dead-time in inverter-fed 5-HP and 10-HP induction motor drives. Experimental measurements are made at different fundamental frequencies and different flux levels (or V/f ratios) to identify if the motor drive exhibits oscillatory behaviour at these various operating points. The regions of oscillatory behaviour of the two motors under no-load are identified experimentally in terms of applied voltage and modulating frequency. A simple dead-time compensation scheme is employed to mitigate these low-frequency oscillations. The experimental waveforms and corresponding Fast Fourier Transform (FFT) analysis of the motor currents demonstrate the sub-harmonic oscillations and their mitigation.","PeriodicalId":308604,"journal":{"name":"2016 3rd International Conference on Electrical Energy Systems (ICEES)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115774554","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}

Twisted pair samples are used to investigate the motor winding behaviour. Modified polyester is the primary insulation here. The primary insulation is subjected to direct testing and the breakdown voltage is determined. Then a secondary insulation layer of nano-composites is coated over the modified polyester layer. The secondary insulation is made in two fold. Primarily epoxy resin is used as secondary insulation and then epoxy resin with filler is used. The secondary insulation was thus made with fillers like Alumina (Al2O3) and Titania (TiO2) of various concentrations added to base epoxy. The direct and withstand tests were performed with these samples coated with secondary insulation. A comparison made between the experiments conducted with primary and secondary insulation shows that the sample with secondary insulation coating was observed to have higher insulation strength compared to the sample with primary insulation. Also the premature insulation failure, caused by the switching frequency produced by power electronic converters have been discussed with respect to primary insulation.","PeriodicalId":308604,"journal":{"name":"2016 3rd International Conference on Electrical Energy Systems (ICEES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125192804","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}
