However, single voltage vector applied in one control period is hard to reduce the power ripples to a minimal value. In order to resolve this issues, the concept of duty cycle control was introduced in FCS-MPPC, which helps to achieve further power ripple reduction. Although better steady state performance is acquired, the control complexity and computational burden are increased when selecting the best voltage vector. In view of this, this paper presents a efficient MPPC(E-MPPC) with optimal duty cycle. The method called E-MPPC only requires one prediction to find the best voltage vector and its duration is determined base on the principle of error minimization of converter voltage vector. Different from prior FCS-MPPC, the computation load of E-MPPC with optimal duty cycle is greatly reduced while the control performance is not affected. Furthermore, the relationship between E-MPPC and FCS-MPPC with duty cycle control is studied and it is found that in some cases, the both methods are completely equivalent. Experimental results on two-level AC/DC converter are presented to confirm good performance and application of the proposed method.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"30 1","pages":"1076-1083"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82398606","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 impedance-based analysis method can be employed to effectively study the interaction stability between grid-connected inverters and grid, which means that it is necessary to obtain the impedance modeling of grid-connected inverters for the analysis of impedance stability. Based on the three-phase LCL-type grid-connected inverter, the harmonic linearization method was adopted in this paper to analyze the frequency characteristic of Phase-Locked Loop (PLL), and a design approach of PLL regulator parameters was proposed. Meanwhile, the impacts of the factors that include PLL and digital control delay on the impedance characteristic were considered, and the positive-sequence and negative-sequence impedance model of the grid-connected inverter was built by combining the harmonic linearization and symmetrical component methods. Then, the frequency characteristic of PLL was verified by the simulation results and the output impedance model of the grid-connected inverter was verified by the experimental results, which effectively proved the correctness of the theoretical analysis. Finally, based on the output impedance model of the grid-connected inverter, the impedance-based analysis method was adopted to make a theoretical analysis and experiment validation of the interaction stability of the grid-connected system.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"75 1","pages":"3606-3612"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76081464","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 converter is based on the switch integration technique, merging the Active-Clamp Forward (ACF) circuit and the HB LLC resonant converter. By adopting the ACF circuit in front of the HB LLC resonant converter, higher input voltage of LLC resonant converter stage can be achieved. As a result, the primary conduction loss can be significantly reduced. In addition, an asymmetric pulse width modulation (APWM) control is applied to cover wide input voltage range and to mitigate the design limitation for a high efficiency and. Consequently, the proposed converter can achieve not only the small conduction loss and the optimal design for high efficiency, but also high power density and low cost due to the switch integration technique. The validity of the proposed converter is confirmed by the experimental results of a prototype converter with 36-72VDC input and 300W (12V/25A) output.","PeriodicalId":6857,"journal":{"name":"2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia)","volume":"63 1","pages":"621-628"},"PeriodicalIF":0.0,"publicationDate":"2016-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88877903","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}
