This paper compares various converter topologies that can be used as unidirectional rectifiers for MV applications (3.5 MVA, 4 kV). The topologies compared in this paper are based on the PLECS simulation results which takes various characteristic plots of the semiconductor devices as given in manufacturer’s datasheets. The comparison results show the superiority of the five-level dual flying capacitor based active neutral point clamped (DFC-ANPC) topology in terms of power density, efficiency and even distribution of losses across the devices.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131354431","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 antenna exploits a pair of orthogonally oriented star shaped monopoles with common ground plane for providing wide multiband characteristics. High isolation (>16 dB) in the suggested diversity system is obtained by employed orthogonal orientation of the monopoles as well as by engraving a pair of slits in the common ground plane. A rectangular parasitic strip is placed behind the monopoles to achieve better impedance matching at 8.1 GHz. The suggested multiband antenna covers three significant bands namely Wireless Local Area Network (WLAN) (5.155.85 GHz), IEEE INSAT/Super-Extended C-Band (6.3-7.27 GHz) and X-Band satellite communication (7.9-8.4 GHz) with a high isolation of ≥16 dB. The spacing between the monopoles is staggeringly reduced to 1.5 mm. The antenna is realized within a compact dimension of 25.3mm×34.80 mm (L×W). The numerical analysis of the diversity parameters shows that the envelope correlation coefficient (ECC) is well below 0.05. The maximum realized gain of the proposed antenna is found to be 4.21 dBi. The consistency among diverse numerical outcomes recommends the candidature of the suggested antenna for multiband wireless diversity applications.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128044383","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 DP plays a key role in the ambipolar conduction of TFET. The proposed device Dielectric Pocket DGTFET (DP-DGTFET) has been demonstrated using a 2D TCAD simulator. The DP length and thickness are optimized to increase the minimum tunneling width near the channel-drain junction, which indeed reduces the ambipolar conduction of the device without affecting the ON-state current, subthreshold swing, and the output characteristics. Moreover, using a high-k material instead of low-k as a dielectric pocket, enhance the device performance in terms of ambipolar behavior. Additionally, the analog performance of the proposed device was also investigated. It is observed that the presence of DP enhances the device performance by reducing the gate to drain capacitance (Cgd); whereas, the presence of gate to drain overlap has a negative impact (increases Cgd) on the proposed device. It is demonstrated that the gate on drain overlap along with the DP in DGTFET enhances the DC performance of the device by reducing the ambipolar current.","PeriodicalId":318478,"journal":{"name":"2020 IEEE Calcutta Conference (CALCON)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114757021","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}
