The proposed converter can provide a very high step-up voltage gain by utilizing dual coupled inductors and voltage multiplier cells. The secondary windings of the coupled inductors are employed to provide the interleaved energy storage in the output side. The voltage and current stress across the power semiconductor devices are reduced. Then the input current ripple is decreased due to the interleaved dc-dc converter in the primary side. In addition, this topology can be operated without an extreme duty cycle or a high turns ratio, and the ON-state resistance ripple is mitigated. The leakage energy is recycled, and the reverse recovery problem of the diodes is alleviated. Furthermore, the performance comparison between the proposed converter and other topologies are explored. The operation principle, mathematical derivations, simulation verifications, and experimental results are introduced. An input of 32-V to an output of 900-V is tested and simulated by using PLECS. Finally, a 450 W hardware prototype is tested to verify the design and the theory.","PeriodicalId":308212,"journal":{"name":"2020 IEEE Kansas Power and Energy Conference (KPEC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133084494","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}

A robust and effective magnetic design help to reduce the parasitic values such as leakage inductance and consequently increase the efficiency and improve the performance of the converters. In this paper, two different HF transformers with different winding arrangements are designed and analyzed. Coaxial windings are used for the transformers in order for obtaining a better magnetic coupling and lower leakage inductance. The results are compared to the regular windings and this comparison showed the effectiveness of the coaxial windings. The design procedure and results are conducted for a power rating of 2kW and a voltage level of 400V/400V at the frequency of 5 kHz. The design method and the analysis procedure used in this paper can later be used for designing optimal isolated DC-DC converters or integrating parasitic parameters in resonant tank circuits for achieving zero voltage switching (ZVS) and zero current switching (ZCS). Especially for converters including silicon carbide (SiC) and gallium nitride (GaN) switches. For analyzing the results and magnetic fields, finite element method (FEM) is used as a numerical strategy.","PeriodicalId":308212,"journal":{"name":"2020 IEEE Kansas Power and Energy Conference (KPEC)","volume":"315 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127071877","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 topologies use the switched-inductor structure to extend the inverter voltage gain. The first proposed inverter can be named the active switched-inductor quasi ZSI (ASL-qZSI). The second topology is the active switched-capacitor/inductor quasi ZSI (ASCL-qZSI). These inverters have the advantage of increased voltage gain per smaller duty cycle and both of them have continuous source current. Compared with conventional enhanced boost qZSI with two switched impedance network (EB-qZSI) the proposed inverters provide high boost ability by one extra switch with less number of components (two capacitors and one inductor are reduced in proposed ASL-qZSI, one capacitor, one diode and one inductor are reduced in proposed ASCL-qZSI). Compared with conventional modified switched-capacitor Z-source inverter the proposed ASCL-qZSI has high boost factor with fewer components in Z-source network (with one extra switch). The experimental results of the proposed inverters with 48 Vdc input voltage are presented to verify the merits of the proposed inverters.","PeriodicalId":308212,"journal":{"name":"2020 IEEE Kansas Power and Energy Conference (KPEC)","volume":"448 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125773729","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}

This is motivated by increasing interests in using D-FACTS devices to address system operational and cyber-security concerns. First, D-FACTS devices can be incorporated in real-time operations for economic benefits such as managing power congestions and reducing system losses. Second, D-FACTS devices can be utilized by moving target defense (MTD), an emerging concept against cyber-attacks, to prevent attackers from knowing true system configurations. Therefore, system operators can use the proposed ACOPF model to achieve economic benefits and provide the setpoints of D-FACTS devices for MTD at the same time. In addition, we rigorously derive the gradient and Hessian matrices of the objective function and constraints, which are further used to build an interior-point solver of the proposed ACOPF. Numerical results on the IEEE 118-bus transmission system show the validity of the proposed ACOPF model as well as the efficacy of the interior-point solver in minimizing system losses and generation costs.","PeriodicalId":308212,"journal":{"name":"2020 IEEE Kansas Power and Energy Conference (KPEC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123482289","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}
