For modular multilevel converters (MMCs), a simple way to improve the efficiency is to drop the switching frequency. Nevertheless, to insure a proper control of the converter, the choice of the modulation method is essential. From this observation, the study throws light on two multilevel modulation methods to estimate their impact on converter efficiency. An average difference of 0.13 % on the total efficiency of the converter is obtained between the two methods, with the possibility of using IGCTs optimized for low frequency operation.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"102 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120863321","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}

Otherwise, a VCB discharging experimental result shows that the proposed method can release more charge from battery than conventional discharging method in this paper. The proposed system composed of several BPMs and a system control circuit can provide energy as a DC voltage source in discharge mode, and can be charged by an external DC voltage source in charge mode. Meanwhile, the characteristics of BPM system such as high flexibility and capability of hot-swapping can be achieved by the proposed system.

However, when it is designed to satisfy a hold-up time requirement, it operates with small effective duty-ratio in nominal state which causes a large RMS current in the primary side. To solve these problems, secondary-side phase-shifted controlled full-bridge converter with a new coupled inductor rectifier is proposed in this paper. In the nominal state, the proposed rectifier uses synchronous rectification to reduce the conduction loss in the rectifier. And, by shifting the phase of rectifier switches, the proposed converter obtains additional voltage gain during the hold-up state. As a result, the proposed converter can be designed regardless of the hold-up time which results in high efficiency in entire load condition. The effectiveness and feasibility of the proposed converter is verified with 320–400 V input and 56 V/12.8 A output prototype converters.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133934534","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 PIV concept comes from the inertia characteristic and swing equation of synchronous generators. It reflects the relationship between the output power and converter internal voltage, the converter response to grid disturbances, and finally, the impact of power converters on the grid stability. In the proposed model, the inputs are the outer controller references and the converter output power, i.e., the power at the point of common coupling (PCC). The output of the model is the internal voltage that determines the grid power distribution, including the power at the PCC. The power will be fed back to the converters as an input, and thinks the closed-loop model of the converter-based system is obtained. Importantly, the parameters of the proposed model are independent of the power grid, but related to the converter operation points and parameters. This makes the model more general and can be employed to analyze multiple converter-based systems. Furthermore, a case study is conducted in this paper to demonstrate the model and the stability analysis.","PeriodicalId":423158,"journal":{"name":"2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127548775","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}
