These techniques may increase the tube life span and they reduce the operating costs with the power RF transmitter. A complete block diagram of the tube power supply unit and an algorithm to control the tube electrodes supply voltages are carried out. The proposed circuit operates the vacuum tube with a decreased filament voltage, withal maintaining the RF output power at the same level as in the normal operation, at the nominal filament voltage. Although the design is intended to be used in Frequency Modulation (FM) RF equipment from particle accelerators, it may be successfully implemented in any power amplifier which uses vacuum tubes.","PeriodicalId":240170,"journal":{"name":"2016 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134240621","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 SRM model is in the form of magnetostatic characteristics of torque, current, flux, and rotor position. To obtain it the numerical open-software simulations and real measurements, based on voltage versus current tests were used.

It has been found that due to an inappropriate orientation (choice) of profession, many young people drop higher education after a year or two of study or they eventually consider themselves professionally unfulfilled. Counseling and orientating high school graduates towards higher education and leading them to a professional career adapted to their skills and abilities is a complex work but which, apparently, does not strike the attention and importance deserved. This article presents a new research which was conducted in February 2016, based on a questionnaire, on a representative group of second year students from the Faculty of Electrical Engineering of Craiova (FEE). It was mainly intended to find out the sources of information and influence of high school graduates about the FEE educational offer, their knowledge on the profession of engineer in the electrical field, framed in a sociohuman context regarding information on the high school graduated, place of residence, parents' educational status, etc., and some suggestions on improving counseling in choosing a career in electrical engineering.","PeriodicalId":240170,"journal":{"name":"2016 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131545729","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}

By a voluntary experimental campaign we aimed at extracting the significant parameters that influence the limb currents (measured at lower leg). Three frequencies in the (30-110) MHz band and two input powers were fed into a biconical dipole antenna, while two polarizations were provided. A group of 15 persons were exposed one by one at 2m distance to the source, in three different postures. Descriptive statistics was applied to separate the field-, the anthropometric- and the postural-connected dosimetric parameters. A resonant body behavior was outlined and introducing of a “coupling coefficient” between body and field was proposed. Generally, the incident field level is not a proper predictor of the limb currents.","PeriodicalId":240170,"journal":{"name":"2016 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123598134","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 method combines the change of injection current on the basis of network analysis technique. The degree of coupling between the various parts of the power grid after the disturbance can be analysed by this method which overcomes shortcomings of ignoring the different operation states when the network technology is applied to the power grid. The proposed index can accurately reflect the influence degree and has a very clear physical meaning. The proposed method is more in line with the actual situation of the power system when compared with the existing complex network model by the application of the IEEE standard sample system. The method is also simulated on the actual central province Power Grid in China, and result shows that the concept of coupling degree is easy to calculate and can real-time track status changes.","PeriodicalId":240170,"journal":{"name":"2016 International Symposium on Fundamentals of Electrical Engineering (ISFEE)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127299051","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}
