Battery chargers must have advantages like high efficiency, more reliable, high power density, low cost, less volume, and weight. Four important factors are barriers in the development of EVs these are 1. battery life and high cost, 2. complexity of chargers, 3. lack of charging infrastructure and 4. chargers introducing harmonic to the utility grid. To reduce cost, weight, and size of on-board chargers, integrated battery chargers are proposed in kinds of literature. Integrated charger topology works with two modes of operation separately, propulsion (motoring) mode and charging mode. In this paper delta connected brushless direct current (BLDC) motor has been used for propulsion mode and same motor stator windings used as coupled inductances for charging mode of operation. In this paper hardware results with boost converter as a power factor correction circuit and MATLAB simulation results of two-channel interleaved boost converter (TCIBC) are presented. Total harmonic distortion (THD) for grid current with a single-channel boost converter (SCBC) 6.68% and simulation results with TCIBC 1.45% respectively. Also, mathematical modeling with delta connected motor is presented and a steady-state voltage gain equation has been derived with TCIBC.","PeriodicalId":422853,"journal":{"name":"2020 IEEE 9th Power India International Conference (PIICON)","volume":"6 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":"129389148","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 poor power quality is mainly a cause of harmonic currents, lower power factor, variation in supply voltage, etc. A UPQC is a Custom Power Devices (CPD) that reduces the voltage and current related PQ problems in the power distribution system. The proposed control algorithm for UPQC is a frequency adaptive loop (FAL) on first transformed module (FTM) of the observer method. As in most Phase Lock Loop (PLL) algorithms, where the transformation of variables into a synchronous reference frame is required to get phase angle detection. Nevertheless, in the case of FTM based FAL, it does not require conversion to estimate phase angle. The angular frequency used to detect unknown estimated parameters and positive-negative elements of the signal under any PQ problems. Another side, the optimal tuned value of proportional-integral (PI) gains are calculated using Firefly algorithm. So, the PI-controller gains are improving dynamic execution of UPQC Controller. The results are captured using MATLAB-Simulink and validated in real time to support the functionality of the UPQC.","PeriodicalId":422853,"journal":{"name":"2020 IEEE 9th Power India International Conference (PIICON)","volume":"vmr-5 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":"127930322","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}

During oil directed (OD) cooling modes, the static pressure drop over the continuous disc type of winding determines the ester oil split among low voltage windings (LV) and high voltage windings (HV) which is connected hydraulically in parallel. In addition, the oil flow distribution in disc type of transformer windings in conjunction with power loss (no-load and load loss) of transformer will decide the location and magnitude of the hotspot temperature in transformer. Hence, there is still a technical challenge with ester oil for transformer manufacturers and utilities to use in large rating power transformers mainly in OD cooling modes. In this paper, the effects of mineral oil and ester oil on frictional pressure, gravitational pressure, oil flow rate, velocity in cooling duct, temperature distributions in top and bottom insulation, main winding zones, core, radiators and coolers are investigated under OD cooling conditions. The typical transformer rating of 60/75/90MVA, 220/33kV is considered for thermal analysis. Since, natural ester oil and synthetic ester oil are potentially different in thermal properties, the thermal analysis results are compared with mineral oil. The thermal hydraulic network model (THNM model) are used for fast calculations of thermal parameters in typical large power transformer. The power losses distributions are calculated from FEM based simulations as an input for thermal analysis.","PeriodicalId":422853,"journal":{"name":"2020 IEEE 9th Power India International Conference (PIICON)","volume":"36 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":"127932488","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}
