The UPS modules system is consists of single master module and multi slave modules. The voltage limitation control is performed to balance the battery modules of UPS system. Firstly, the master module checks the SOC of UPS modules to make order according to SOC. And, the master module calculates points to limit output voltage to control output power of the modules. Finally, the output voltage becomes sum of output voltage of UPS modules because of the series connection. As a result, the utilization of the battery can be increased in series connection UPS system.

Although various technologies can overcome high short-circuit level problems, none of conventional solutions provides extra transmission capability or ability to control or redirect the power flow. In this paper, the solid-state fault current limiter (SSFCL) will be investigated for transient stability enhancement of practical large-scale power systems. A controllable resistive type fault current limiter (CR-FCL) is first developed for comparative studies. A single DC reactor fault current limiter, which does not require switching device or control system, is then proposed for lower cost and simple operation. Circuit configurations and corresponding simulation models in real-time simulation environments will be investigated in details. By proper locating the transient limiters, transient stability enhancement can be demonstrated through real-time simulator OPAL-RT.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"2005 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131384744","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}

By replacing the common inductors of the classical Z-source impedance network by two improved 2-terminal STL cells that are derived from SL and TL cells, the output voltage range of Z-source inverters can be further expanded. Compared with the classical Z-source inverter, along with SL/TL Z-source inverters, the proposed topology increases the voltage boost inversion ability significantly, and only a very short shoot-through zero state is required to obtain high voltage conversion ratios. A detailed theoretical analysis is given under steady-state and the analytical results are validated by the simulation examples using simple boost control and the maximum boost control method, respectively. The proposed STL concept can also be extended to the topologies of quasi Z-source inverters. Two extended configurations, quasi TL Z-source inverters are presented for reference, which can further improve the circuit characteristics.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"120 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124514107","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}

One drawback of burst mode control is that the burst frequency changes with different load, which would introduce audible noise to the system. In order to solve the frequency variation problem of burst mode controlled converters, a parabolic voltage control method is proposed in this paper. By the use of a pair of parabolic carriers as the control bands, the burst frequency is controlled to be constant and audible noise can be eliminated. The derivation of the proposed parabolic voltage control is conducted and operating principles are discussed. The performance of the proposed control method is experimentally verified by the use of a burst mode boost converter.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132357146","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}

Advantages of using soft-switching are its high efficiency and high switching frequency, thereby reducing switching losses, while one of its disadvantages can be the complicated circuit. The power board, a printed circuit board whose wiring patterns are made of thick copper, is employed for its two main advantages. 1) It can flow a large amount of current and 2) it can have complicated circuits.

By contrast, variable step-size MPPT can achieve satisfactory tracking accuracy and speed while maintains advantage of simple calculation. This paper aimed to study the performance of two different variable step-size P&O MPPT techniques. Initially, a MATLAB based PGS model is implemented and validated.
