In order to simplify system configuration, reduce cost, and improve conversion efficiency, this paper aims to develop a step-up/down inverter by adopting a boost-interleaved buck-boost (BoIBB) dc-dc converter and connecting with an H-bridge unfolding circuit with line-commutated operation. The proposed circuit can work functionally as either step-down or step-up inverter so that it is suitable for the applications with wide voltage-variation. Due to operating with buck or boost principle, partial energy can be directly delivered to output to improve efficiency. Besides, since only one power switch operates with high-frequency at one time, switching losses can be significantly reduced. Furthermore, high input current is shared by two inductors during step-up mode, leading to the reduction of conduction losses. Finally, a laboratory prototype with 110 Vrms / 60 Hz output voltage is then implemented accordingly to verify the validity and feasibility of the proposed inverter.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"136 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":"123815229","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}

It was reported that the NDZ of frequency drift anti-islanding is enlarged with closed-loop based constant power controller. On the other hand, some research gives the functionality of the frequency drift anti-islanding even with the closed-loop power controller. If the principle of frequency drift is carefully considered, the positive feedback loop should be modified to maintain the performance of the conventional frequency drift anti-islanding when the cascade outer (power control) loop is constructed. And the NDZ of modified loop would not be degraded by the outer loop. In this paper, the rationale of the modification of the closed-loop is discussed. And, it is shown that the modified feedback loop doesn't degrade the performance of the frequency drift anti-islanding with the closed-loop power controller. The performance of modification is verified by computer simulations and hardware experiments.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"12 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":"121533583","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}

With applying to a multi-level topology, the voltage stress is reduced in all switches. In addition, the low order harmonic components are reduced due to five-level waveform. In a two-level DAB converter, the efficiency becomes low when the input voltage is not closed to the nominal voltage. In order to improve the efficiency at the input voltage fluctuation, this paper also proposes the operation mode of the three-level DAB converter at the input voltage fluctuation. The output voltage waveform of the inverter is determined by the relationship among the efficiency of the two modes which are so called the full-bridge mode and the half-bridge mode. In this paper, the changing point between the half-bridge and the full-bridge mode is derived using the loss calculation. In the simulation, the ZVS range and the inductor current are compared with the two-level and the three-level inverter. It is confirmed that the ZVS range is extended by 60%. In addition, the fundamental operation of the proposed DAB converter is confirmed by the experimental results.","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":"127926330","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}
