Unless a major technological breakthrough is achieved in energy storage and battery technology, EVs future will pass by multiple energy sources hybridisation, to benefit from the best characteristics of the energy sources available. In this paper, the energy and the mobility problems are introduced as well as the relevance of EVs in advanced and sustainable transportation. The EVs energy management issue is addressed together with the need for multiple energy sources hybridisation. Finally, a detailed description of the multiple energy sources monitoring system, particularly of its sensor data acquisition network, developed by the authors for their EV prototype, is presented along with collected data drawn from tests to one of the EV battery banks.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133197945","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 study aims to develop an estimator which gives good stator flux feedback values even when the stator resistor varies with the machine temperature. In DTC algorithm, stator electric equation is usually used to calculate the stator flux error. The value of this error is used with the torque error to determine the optimal voltage space vector that gives a simultaneous changing of the torque and the flux in the desired direction. The accuracy of the DTC depends on the proper calculation of the stator flux. The main objective is to build a stator flux estimator depending on the rotor electric equation. Since the time response of the rotor flux is bigger than the time response of the stator flux, this new estimator is less sensitive to the variation of the rotor resistor. The behaviour of the developed estimator is enhanced in an adaptive way to take into account the variation of the saturation level in the air gap of the induction machine.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124297333","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 analysed oscillations occur particularly in electrical drive systems with active front end, common DC-link and long shielded motor cables. Because of resonant frequencies at 10 to 40 kHz low damping occurs. In the concerned frequency range switching operations generate a significant excitation. As the focus of this paper the common mode system of an electrical drive system is analysed and modelled. The damping behaviour of the choke and the switching of active front end and inverters have to be analysed very carefully. Simulations and measurements show apparent voltage stressing of motors, common mode losses and currents that disturb the drive system.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133833407","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}

On the web dynamics itself, lumped parametric expressions may be used to designate a web section between two adjacent drive rolls, and there is the necessity to incorporate the property of visco-elasticity to the web. In this paper the lumped model of a new web tension experimental system is updated; the model is based on the conservation of mass, torque balance and viscoelasticity (Voigt approach). The experimental system consists of four sections, each of which is driven by a servomotor with the speed and tension feedback, by using encoders and tension sensors. Usually these kinds of models are developed in the Laplace domain and the block scheme gives a graphic interpretation of the interaction between different sections. The block scheme transformation in a differential equation system in the time domain is considered in this paper; it requires the introduction of nonzero initial condition for the derivative of physical variables. The problem of validation has been dealt with in detail in this paper, simultaneously considering 2 different combinations of input data in open loop and a multivariable optimization method in order to estimate the unknown parameters. The results will show the accuracy of this kind of lumped parameters model for the complex experimental systems and useful information for successively designing an efficient control strategy.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122529304","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}

To realize the stability analysis, a model of shipboard power station voltage control system has been determined, moving from dynamic models of alternators, voltage regulators and loads. Reduced order models of alternators have been utilized, to simplify at best the analysis. Analysis results have been validated through numerical simulations, using a simulator of power station electromechanic quantities developed at the University of Trieste. Such simulator includes alternators, voltage and frequency regulators, breakers, protections and R-L loads. Numerical results obtained from simulations of both complete and reduced order models fully validate the analytical findings, while computation times are in the order of real-time simulations.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122796003","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 particular, the dV/dt characterization test is described and, afterwards, specific electrical tests are provided to explain the root causes. From the electrical results point of view, the dV/dt slew rate does not involve an intrinsic bipolar transistor turn-on, as usually assumed in these kinds of failure. Instead, a gate oxide degradation occurs causing the device to fail as a result of dV/dt repetitive events. Such kinds of gate oxide degradation were observed measuring the threshold voltage degradation after an established dV/dt train of impulses till the failure occured. Afterwards, the same train of impulses was implemented on a new series of samples, changing the circuit and, in particular, inserting a resistor in the gate electrode. In this test, no failures were observed, even if several repetitive trains of impulses were supplied.","PeriodicalId":345557,"journal":{"name":"2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121168980","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 proposal is replace the single-phase motor by a three-phase motor, in the conventional refrigeration system. In this way, a proper control technique can be applied, using a closed-loop (feedback control), that will allow an accurate adjustment of the desirable temperature. The proposed refrigeration prototype uses a 0.5 Hp three-phase motor and an open (Belt-Drive) Bitzer IY type compressor. The input rectifier stagepsilas features include the reduction in the input current ripple, the reduction in the output voltage ripple, the use of low stress devices, low volume for the EMI input filter, high input power factor (PF), and low total harmonic distortion (THD) in the input current, in compliance with the IEC61000-3-2 standards.
