Due to large numbers of loads are single-phase loads in microgrid, it is difficult to maintain three phase loads in the actual system keep the same and thus system loads resemble unbalance. Furthermore, this load unbalance is a dynamic variation because loads switching on or off is random, which will cause output voltage of microgrid inverter unbalanced. In order to improve the dynamic unbalanced performance of microgrid inverter, a feedforward control strategy is proposed in this paper. With this control strategy, inverter can instantaneously compensate unbalanced voltage and always keep output voltage balance even if there is a sudden large load change. Simulation results verify the feasibility and validity of the proposed control strategy.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115230255","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, the load power may reach to millions of watts, and the starting current of trains may reach to thousands of amperes, which may lead to the high cost and volume of DCAT system. To evaluate whether DCAT system is feasible in the DC railways with high power and high current, the power analysis of DCAT system is proposed in this paper. The mathematical analysis and the relationships between the capacity of each DCAT and the load power are discussed in detail.

In this paper, a new modulation scheme for this topology is presented, where always only one out of three rectifier half-bridges is pulse width modulated, while the remaining two phases are clamped and therefore a higher efficiency is achieved. This modulation concept with a minimum number of active half-bridges, denoted as 1/3 rectifier, becomes possible if in contrast to other modulation schemes the intermediate DC link voltage is varied in a six-pulse voltage fashion, while still sinusoidal grid currents in phase with their corresponding phase voltages and a constant battery output voltage are obtained. In this paper, a detailed description of the novel 1/3 rectifier's operating principle and the corresponding control structure are presented and the proper closed loop operation is verified by means of a circuit simulation. Finally, the performance gain of the 1/3 rectifier control scheme compared to conventional modulation schemes is evaluated by means of a virtual prototype system.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115722946","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}

Compared with bidirectional traditional cascaded DC/DC converter, this new converter is also composed of two conventional two-level DC/DC converters. However, the two two-level converters in this converter are connected in parallel on the input side rather than in series. In addition, the voltage gain of the proposed converter is higher than bidirectional traditional cascaded DC/DC converter, because this new converter establishes the higher charging voltage of inductor in the step-up mode, which makes the inductor store more energy and transfer more energy to the high voltage side. Besides, the high voltage sides of the two converters are connected in series to constitute the whole high voltage side of converter, which further enhances the voltage gain and reduces the voltage stress on the power switches and capacitors. The operating principle and the steady-state analysis are presented detailedly in this paper. Finally, a 400W experimental prototype of the proposed converter is developed to verify the correctness of the theoretical analysis. The maximum efficiency of the converter is 95.23% in step down mode and 94.54% in step up mode.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121080059","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}
