This technique can be implemented with the system with an incremental encoder or sensorless system. The results are the proper starting phase and exact starting rotor position. The phase winding is energized by the narrow voltage pulse then phase currents are detected and calculated to find the rotor position by using the cubic spline interpolation technique. The proper phase is chosen for a starting phase. This proposed idea is done in the MATLAB/Simulink program.","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":"126794461","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 authors propose the line inductance compensation control and the line voltage compensation control which can be applied to the loop distribution system according to the line parameters.

The power is transmitted through dc distribution line and converted to required ac or dc voltages by converters placed near loads. Those load side converters do not need transformers by choosing proper dc distribution voltage (plusmn170 V). The dc power line is composed of 3 wires: +170 V line, neutral line and -170 V line. The distribution voltages have to be balanced to keep high quality power supplying. In this paper, a voltage balancer for dc distribution are proposed and studied. Computer simulation results demonstrated that dc micro-grid was able to supply both ac and dc power to loads simultaneously and stably by 3-wire dc distribution line and load side converters. In addition, another voltage balancer (dc/dc converter type) is also proposed and studied in the last section.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"12 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":"128136839","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}
