In order to design the magnetic pads, a new model must be set up for every pad and the number of simulations increases exponentially which is very time consuming. This paper focuses on the EV application and presents a method of reducing the number of required simulations. The analytical calculations can be used to optimize the coils without ferrite and the finite element method (FEM) can be used to optimize the coils with ferrite. Since the results show that the coils with ferrite and coils without ferrite have the same trend of variability of coupling coefficient with varying physical size and coverage, an optimization method of magnetic pads is proposed to combine analytical calculations with FEM simulations. First the physical size of coils and the coverage of coils are optimized by using the analytical calculations. Then FEM simulations are used to optimize the ferrite arrangements and determine the coil turns. The method is confirmed via simulation validations.","PeriodicalId":335893,"journal":{"name":"2018 IEEE 4th Southern Power Electronics Conference (SPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128918885","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 system is properly designed for electric motor drives in building applications. However, the proposed system can also be applied in any other building applications by slightly changing the control algorithm. The high motoring reliability in the suggested system is attained by evaluating the performance of each SC and BT considering the history and the HESS operation. The high equalization reliability is achieved through a new topology and a control algorithm that properly manage an auxiliary SC-based ESS which serves as a backup energy bank in order to provide the required energy in any weak cells of the main HESS for equalizing their voltage as well as enhancing the dynamic performance of the main application. The effectiveness of the proposed monitoring and equalization control scheme has been validated by several simulation results that are extensively discussed throughout the paper.","PeriodicalId":335893,"journal":{"name":"2018 IEEE 4th Southern Power Electronics Conference (SPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128976883","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 diversity of grid-connected power converters with various control strategies complicates the analysis of system dynamics, when various and detailed converter models are adopted. This paper thus proposes a universal model of grid-connected converters that can reflect the essential power-internal voltage characteristics. With that, the diversity of converter outer controllers may be discarded, as their dynamics can be represented by the deviation of active and reactive power. In the proposed model, the transfer functions from the converter output power to the internal voltage and to the Phase-Locked Loop (PLL) output frequency are obtained, enabling the exploration of the stability of the internal voltage and the PLL performance. An example system is adopted to demonstrate the proposed model and simulated in PSCAD/EMTDC. The results show that the model is accurate to reflect the impact of controller parameters on the power-internal voltage stability of the entire system.","PeriodicalId":335893,"journal":{"name":"2018 IEEE 4th Southern Power Electronics Conference (SPEC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678674","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 methodology of this paper is based on the three-phase Permanent Magnet Synchronous Motor (PMSM) model with Field Oriented Control (FOC) and with the flexible load model. The resonant part is estimated with two approaches. The first one is the Recursive algorithm of the Least Squares Method (RLSM) and the second one is the Spectrum Analysis (SA), from their results the compensators are constructed in the discrete form for the implementation in a digital control system. In the case of the RLSM, the compensator is obtained as the inversion of the gained model of the resonant part in the discrete form. The compensator from SA is obtained as the result of iterative algorithm, where for each iteration there is gradual calculation of the compensator numerator and denominator The results of both experiments are contrasted with the resonant part of the model, to show the independency of the algorithms on the electrical part of the motor. The Pseudo Random Binary Sequence is used as the input signal for the identification experiments. Finally, the capability of the obtained estimates as the resonance compensators is evaluated in the final part of this paper Both presented methods are capable of the use for the self tuning algorithms.","PeriodicalId":335893,"journal":{"name":"2018 IEEE 4th Southern Power Electronics Conference (SPEC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131947833","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}
