The coupling effect of the inverters makes it complex to analyze the resonant characteristics of the multiple grid-tied inverters, especially between inverters of the different type. An increasing number of parallel converters makes the coupling effect more serious. Based on this, a method of decoupling and simplifying the coupling effect of multi inverters is proposed. First, the output current of the inverter is separated and the resonance characteristics of each part are analyzed. Then, the relationship between the interaction current resonance of the multiple grid-tied inverters and the overall current harmonic oscillation of the network is obtained. Finally, a simulation model is built on the Matlab/Simulink platform, and the correctness of the conclusion is verified by simulation.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"42 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":"122082714","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}

Circulating current with a second-order harmonic component is one of the pivotal issues in controlling MMC, since it will result in higher arm current and power loss in either upper or lower arm. A direct digital control is proposed to track inductor current command tightly regardless of wide filter inductance variation and to eliminate circulating current. In this paper, an MMC configuration is introduced first, and then a direct digital controller for circulating current suppression is derived in detail. Simulated results obtained from a 120 kW MMC have verified the analysis and discussion.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"23 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":"126101569","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}

Many previous studies focus on the suppression of SSCI by flexible AC Transmission System (FACTS) devices. This paper proposes a new static synchronous compensator (STATCOM)-based SSCI mitigation algorithm to increase the stability margin of wind farms. Admittance model of STATCOM with Supplementary Damping Controller (SDC) is derived and it is proved that the controller provides extra damping to the system. Relationships between the controller parameters of the SDC and the damping performance are discussed and the results are validated by simulations with PSCAD/EMTDC. Finally, the impacts of a three-phase fault close to the wind farm is investigated and the resonance can also be alleviated by the SDC under this situation.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"40 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":"130059068","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}

To know the exact performance difference between SiC MOSFET and SiC BJT, in this paper, a comprehensive comparison between SiC MOSFET and SiC BJT with same voltage and current rating was experimentally investigated under different conditions. At first, we measured all parts of power losses consumed on the power devices in different input voltages, load currents, and operation temperatures. The power losses analysis results show that even though the SiC BJT has smaller turn-off loss and conduction loss than its SiC MOSFET counterpart, the larger turn-on loss and driver loss still make the overall power losses a little larger than SiC MOSFET. Then based on the power losses analysis, we evaluated their maximum power handling capability by comparing the conduction current in a 100kHz fixed input voltage DC/DC boost converter with same temperature margin taken into account. It is experimentally verified that the SiC BJT can stably handle 10A current at $T_{c}=136^{circ}mathrm{C}$ while the SiC MOSFET only can handle 7.6A at $T_{c}=110^{circ}mathrm{C}$ when considering $40^{circ}mathrm{C}$ temperature margin, indicating that the SiC BJT has larger power handling capability because of its more excellent temperature durability.","PeriodicalId":446770,"journal":{"name":"2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC)","volume":"25 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":"129031354","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}
