The diesel engine changes the speed according to the load of the set. The optimum speed is hereby calculated according to the load of the EGS with as the optimality criterion the minimum fuel consumption. The analysis of the dynamic behavior of such new EGS concept shows some new problems with power and voltage drops at sudden increase of the load. The dynamical properties of EGS concept with variable speed technology could be improved by using an energy buffer. Solutions of concept EGS with the energy buffer and their advantage or disadvantage are discussed in this paper.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131274411","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 case of the three-phase construction, the duty-cycle of this converter is extended to three times of that of the typical buck converter because the voltage conversion ratio is given as V0/Vi = D/3. The switching loss and switching stress are reduced sufficiently because the switching operation is achieved by one-third of the input source voltage (Vi/3). The current ripple of the output smoothing capacitor is the same as that of conventional five-phase buck converter. The current unbalance between the respective phases is removed automatically and completely without any current sensing means. The above fine characteristics are simply achieved with two additional capacitors.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116453204","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 order to do this, the conditioner is able to transfer power between its phases through a common dc link. Besides load voltage conditioning, the studied system has a power conditioner at the source side that makes source current conditioning. The function of this source-side current conditioner is to provide a balanced three-phase current to the source. Power circuit configuration and control strategy are presented. Computational simulations in the time domain of various situations associated to a typical operation of an electrical system were performed and are presented. Large motor starting with meaningful voltage drop is considered in the study. This study was intended for developing alternative concept on electric power supply for future offshore oil production systems.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"49 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120833737","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 powered terminal needs to separate ac communication signals and dc supply power in its input part connected to the communication lines. In our communication system, it is preferable that the electronic choke be bidirectional. So, we have already proposed a low-loss electronic choke with small inductors and an amplifier. This circuit can be also used in the powering terminal. The electronic choke has high input impedance against communication signals. The frequency range of acceptable signals is determined mainly by resonance frequency of the inductors. In this paper, a method fitting this frequency range to the communication signal is proposed. To realize this, we introduce an inductor having new structure and external connection. By the effective use of electric coupling and magnetic coupling in windings, input impedance of the electronic choke is increased.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129133783","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}
