The performance of AC and DC distribution systems are compared. Models account for the variable efficiencies of power converter blocks as power levels vary. A control strategy is developed to choose when/how many EVs charge based on available PV power thereby maximizing efficiency and solar energy usage in the EVs. It is shown that for an EV user with a home charge point and a 100 km daily return commute, a ~90% SOC can be supported by the system during the summer months. It is also shown that the DC system is 4.67% more efficient than the AC system over the course of a year.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130047873","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 this paper, a compact non-isolated bidirectional DC-DC converter is proposed to interface two input DC power sources. The proposed converter is proficient for energy diversification from two energy sources individually or simultaneously. It can be operated bidirectionally in both buck and boost modes. With comparison to traditional double inputs boost converters, only three controllable power switches are needed in the proposed converter, which is much cost effective. The topology is analysed in detail and a control algorithm are proposed to operate the converter. Simulation results are presented to verify the validity of the converter.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134261725","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 proposed network uses a tightly coupled transformer with three windings. By squeezing the shoot-through range while keeping higher boost, the inverter can operate at a higher modulation index, thereby minimizing switching device stress and providing better output power quality. In addition, the inverter has more degrees of freedom for setting the voltage gain and modulation index than other classical impedance-source networks. This design flexibility was proven mathematically, and is supported by simulations carried out to prove the concept and validate the analysis.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124874683","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 use the advantages of dc also in medium-voltage applications a highly efficient dc-dc converter is needed that has a power capability of several megawatts. At the E.ON Energy Research Center of the RWTH Aachen University a demonstrator for a 5 MW medium-voltage dc-dc converter is constructed, which is presented in this work. Firstly, some general considerations about the three-phase dual-active bridge dc-dc converter are made, with a focus on medium-voltage high-power applications. Whether IGBTs or IGCTs are the optimal switching devices is discussed and a further improvement using a Dual-ICT is evaluated. The construction and the design of the mentioned demonstrator are presented. Besides the demonstrator itself, the medium-voltage high-power transformer that is operated in the ac link is discussed in detail. Finally, the advantages of a three-phase dual-active bridge over the single-phase variant are discussed using the experience gained from the commissioning.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115031460","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 proposed topology has an active decoupling function, which not only eliminates the double line frequency ripple power in the dc-link but also accepts large voltage ripple across the decoupling capacitor in order to reduce the requirement of the decoupling capacitance. Traditionally, bulky electrolytic capacitors are employed in passive decoupling of power, which limits the system lifespan. The reduction of the decoupling capacitance makes it possible for using long life film capacitors in photovoltaic systems. The simulation results verify the operation of the proposed topology and its control strategy.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124577635","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 non-sinusoidal nature of the current and voltage waveforms commonly present in power electronic converters makes it difficult to accurately evaluate the copper and core losses of components such as inductors and transformers operating at high and medium frequencies. The evaluation of the core losses for three soft magnetic materials (amorphous, ferrite and nanocrystalline) under different rectangular-voltage waveforms used in solid-state transformers, duty cycles and switching frequencies is the main aim of this work. The test setup comprises a 10 kVA Si IGBT-based three-level full-bridge converter used to generate the rectangular-voltage waveforms exciting the cores. The comparison based on the main material properties establishes criteria for proper core material selection when designing high-and medium-frequency transformers.","PeriodicalId":448765,"journal":{"name":"2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116283337","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}
