The AEPS spacecraft operates at High Thrust, Low Specific i mpulse (Isp) and/or Low Thrust, High Isp modes to meet the mission requirements. The power processing unit feeding the electric thrusters are to be designed for wide load and line variations. Dual active bridge (DAB) converters are becoming popular in Aerospace and AEPS missions. Aim of this work is to develop a novel control scheme and analytically prove that higher efficiency (thru minimum RMS or peak current) and improved performance (thru increased ZVS range) can be achieved over entire AEPS operating regime. In this paper, a novel modulation scheme called Combined dual modulation scheme (CDMS) is presented. The analysis of the same is presented and the performance is verified in terms of RMS, peak inductor currents and ZVS operation of DAB converter. The control scheme is verified for simulation of DAB converter feeding a 1 kW - 5 kW system. The CDMS features better configurable output stage, wide output voltage range, high efficiency, higher power density and reduced Electromagnetic interference (EMI).","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"379 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131075948","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 paper emphasizes a simple yet powerful modeling and electromagnetic analysis of a dc-biased excitation transformer used in a hydropower plant. The three-dimensional modeling of the excitation transformer was carried out using the transformer constructional details and analyzed using Ansys Maxwell. The finite element method was used to analyze a three-phase 500 KVA excitation transformer. The impact on the excitation transformer was investigated for varying levels of dc bias with different excitations. The simulation results include various plots of variables and the loss characteristics. This research provides new insight on the importance of accurately calculating the losses of an excitation transformer under dc bias during the design stage. The main contribution of this research is a simple approach for performing the electrical and magnetic analysis of a dc-biased excitation transformer, which could be helpful for designers in determining the effects of various variables and can be adequately addressed during the designing stage.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"10 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132899276","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 converter structure is formed using $n+1$ inductors, $n+1$ capacitors, and $2n+2$ MOSFETs, just like the conventional n-stage BQBC. The current and voltage stress reductions are achieved in the proposed n-stage BQBC by using a cascaded leg arrangement of the MOSFETs that are formed using $n+1$ MOSFETs out of the total MOSFETs. This stress reduction leads to reducing the rating of $n+1$ MOSFETs and improving the efficiency of the BQBC. The steady-state analysis of the BQBC with $n=1$ is presented in this paper. The components are designed for 200 W, 350 V, and 20 kHz with a source voltage of 48 V. The effect of parasitic elements on the output voltage and the efficiency is investigated. The experimental results of the BQBC are observed using the laboratory prototype and are presented. The performance comparison is carried out with the recently reported converter and BQBC. In addition to reducing stress and increasing efficiency, the main benefits of the proposed BQBC are a continuous source current and a common ground between the input and output ports.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133008790","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 concept of leasing the rooftop area to a solarbased company is demonstrated. The SPV system facilitates local loads' uninterrupted power supply (UPS). This system performs seamless mode change operation, power quality enhancements, energy surety, and renewable energy source (RES) integration. A distributed static compensator (DSTATCOM) is used with an efficient and novel current control technique in the on-grid mode and a voltage-control technique in the off-grid mode of operation to achieve seamless and reliable operation in different modes. In on-grid mode, the company sells the surplus energy to the utility grid/nearby private customers to make a profit. However, in the off-grid mode, the local loads of the rooftop lender are given in priority. The seamless mode-change operations of the SPV system are carried out using a synchronization control and a solid transfer switch (STS). The results from MATLAB simulations and developed hardware prototype validate the system performance according to the IEEE-519 and the IEEE-1547 standards.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131981053","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 21-level inverter designed to used only three input DC-link voltage sources and ten power electronics switch to obtained higher voltage level, better utilization of dc sources is also obtained, which can improve inverter TSV, cost, and efficiency. Thus, the number of DC sources is maintained smaller and is utilized so that the peak output voltage is nearly the sum of the input dc voltages. In addition, the output voltage levels are obtained by addition and subtraction of the input dc sources, which lower the number of dc sources and the inverter TSV. Moreover, the number of conducting switches is much lesser of the others MLIs, which results in smaller conduction loss and better efficiency. A carrier-based level-shifted PWM (LSPWM) technique is implemented using DS1103 based digital controller for the inverter. Finally, the experimental results of the inverter with dc-link voltage ratios are presented for RL load. Moreover, the performance of the MLI is compared with the existing MLI topologies.","PeriodicalId":161541,"journal":{"name":"2022 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132169906","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}
