An on-line trained ANN serves as a speed controller and does not need a process model to predict future performance. In comparison to the previously published solution, auto-adjusting ability has been added to the controller. The recurrent feedback inside the neural controller has been also introduced. Adaptive behaviour manifests in robustness to moment of inertia variation greater than 10 times. This feature is achieved by the learning algorithm running during system operation. Mentioned variable update period refers to one of the parameters connected with learning algorithm, namely frequency of calling backpropagation procedure (weights update procedure). Proposed control algorithm has been tested in simulation and verified experimentally. The behaviour of the drive has been compared to the one with previously proposed ANN-based speed controller with fixed settings of training algorithm.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"360 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126695819","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 input disturbances, such as voltage unbalance and voltage harmonics, are considered as perturbations of the fundamental component, and a small-signal analysis is used to determine the spectrum of the line current. The proposed analytical approach has a general validity, because it takes into account the effects of the line and filter impedance, the supply harmonics and the input current modulation strategy as well. Hence, it could be usefully employed to evaluate the line current quality in the point of common coupling for different filter topologies and supply distortions. Experimental results are given to confirm the analytical solution.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121294039","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, turbocharged engines exhibit a relatively low torque capability at low engine speeds. To overcome this problem, an electrical torque boost may be applied whilst accelerating and changing gear, and to facilitate energy recovery during regenerative braking. The paper describes the operational requirements of such a torque boost system, which employs a supercapacitor energy storage buffer, outlines the design and sizing of the electrical machine, and presents test results from a demonstrator system.","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121550851","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}

These losses depend on the modulation frequency and on the drive output power. The change of modulation frequency modifies converter losses and also motor losses, because of the modified motor current waveform. Thus, it modifies total drive losses. Variation of the drive output power also modifies total drive losses and can be problematic when the drive operates in the field-weakening region. The paper presents a complete analysis of motor losses, converter losses and losses of the entire drive in the field-weakening region of an open loop controlled induction motor drive supplied by a voltage source inverter. Losses are presented in dependence of the voltage source inverter output frequency and the drive's output power. Presented results show that the modified voltage to frequency ratio causes an increase of the total drive losses in the region of high frequencies and high output powers. The paper also presents an analysis of the impact of modulation frequency on drive losses","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114235313","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 most applications a special DC-to-DC converter is necessary to couple the solar cells, operating at low DC voltages, to the inverter's DC-link. These converters with rather low input respectively high output voltage ratings have, due to the high current ratings, a relatively low efficiency. Therefore, a special design is required to adapt the different voltage levels and fulfil the requirements of loss reduction. In this paper, a possible solution for such a specific solar converter is presented: a DC-to-DC converter with a controlled active snubber circuit. The input voltage of a (e.g. battery buffered) solar array (12 V or 24 V) is adapted to a 400 V DC-link, for a local grid power inverter supply. The total power to be managed on the output of the DC-to-DC converter is 500 W (12 V) respectively 1 kW (24 V) in our case. So it makes sense to develop a topology which is also well suited for paralleling several power switches. The structure presented here fulfills all of these topics","PeriodicalId":401288,"journal":{"name":"2006 12th International Power Electronics and Motion Control Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122847105","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}
