To reduce power dissipation at lower technology nodes, digital logic circuits are designed with modern (FinFET) devices. In this paper, FinFET INDEP (input dependent) technique-based short gate (SG) FinFET Adder circuits are proposed at 10 nm technology node. The performance comparison of INDEP technique-based adder circuits is done with the SG FinFET adder circuits. The analysis of adder circuits is performed first in terms of functional verification (transient characteristics) and finally for different performance parameters such as propagation delay, power dissipation and power delay product (PDP). The proposed FinFET INDEP technique proves as one of the best leakage reduction techniques for FinFET adder circuits at lower technology nodes. To test the reliability of the circuits, Monte Carlo analysis is also performed. The PDP is improved by 16.8% and 13.73% in INDEP SG FinFET half adder(HA) and INDEP SG FinFET full adder(FA) at 10 nm technology, respectively, in comparison with the ones without INDEP technique. The Monte Carlo simulation results with 3σ Gaussian distribution at ±10% process, voltage and temperature variations show the improvement in PDP in case of SG INDEP FinFET FA and SG INDEP FinFET HA circuit in comparison to SG FinFET FA and FinFET HA circuit, respectively. Simulation is performed using HSPICE tool at 10 nm process technology node.","PeriodicalId":34935,"journal":{"name":"Australian Journal of Electrical and Electronics Engineering","volume":"20 1","pages":"1 - 12"},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85664625","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}

Hence, to hold this kind of technologies, the distribution systems in the future have to be converted to AC–DC hybrid for considering all kinds of DGs and (DC and AC) of loads. This paper attempts to develop an integration of DG with AC–DC hybrid distribution systems connected with solid state transformer (SST). The main intention of this paper is to make an energy-efficient system, by enhancing the voltage profile, reducing greenhouse gas emissions and reducing real and reactive power losses, when DG with SST is connected to a hybrid distribution system. With these constraints, a multi-objective function is formulated, which is solved by a new improved meta-heuristic algorithm in optimal location and sizing of DG. The new algorithm adopted in this paper is the improved Rider Optimisation Algorithm (ROA) termed as Fitness Rate-based ROA (FR-ROA). The experimental analysis on single and multi-objective functions proves the efficacy of SST in providing an energy-efficient system model.","PeriodicalId":34935,"journal":{"name":"Australian Journal of Electrical and Electronics Engineering","volume":"51 1","pages":"324 - 339"},"PeriodicalIF":0.0,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73170870","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 foremost drawback of DTC induction motor drive is high torque pulsation, variable frequency of inverter switching. The main reason of torque pulsation is torque and flux hysteresis band utilised in DTC. DTC method is utilising hysteresis comparators which produce high torque pulsation and unpredictable switching frequency. In this paper, torque ripple analysis of fuzzy logic controller (FLC) based Direct Torque Control (DTC) of three-phase induction motor drive has been discussed. The space vector pulse width modulation (SVPWM) based DTC technique, which operates with the regular switching frequency, helps to solve the fundamental issues of torque pulsation. In addition to this, literature proposes different solutions like a prediction scheme, fuzzy logic controller technique, global minimum torque ripple strategy, constant frequency torque controller (CFTC) Technique, optimal switching instant scheme, duty cycle control scheme, SVPWM DTC for torque ripple reduction. The fuzzy logic controller capabilities for DTC technique are applied with the induction motor (IM) drive for high-performance applications. The simulation results of Conventional DTC, SVPWM DTC, Carrier SVPWM DTC and FLC-DTC method for the induction motor are illustrated. Fuzzy-based DTC technique compared with CSVPWM DTC method and conventional DTC method are presented. The torque ripple of 7.4% for 5 HP induction motor is achieved by FLC-based DTC method. Hardware results for DTC induction motor drive are also demonstrated and discussed.

Conventional MPPT algorithms are not efficient enough to follow the maximum power variable irradiation and temperature conditions. Therefore, an intelligent algorithm has been required to extract the maximum power in a standalone PV system. The present paper incorporates adaptive intelligent maximum power point tracking (MPPT) method adaptive neuro-fuzzy inference system (ANFIS) techniques to extract maximum voltage and power. The fuzzy logic controller (FLC) has been implemented to analyse the performance compared to the ANFIS method. Because of the utilisation of conventional techniques, the point of maximum power gets oscillated in a low irradiance level and the values move between forward and backwards but do not have a fixed value. The used ANFIS method takes all the possibility values from 0 to 1, increasing efficiency. The efficiency of the ANFIS-based MPPT method is 90% more accurate than those of other conventional methods, which has been presented in the paper. For the remote monitoring of the obtained voltage, current and power, internet of things (IoT) features have been incorporated into the considered standalone PV system. The presented standalone PV system has been experimentally verified and validated for the efficiency evaluation of the proposed ANFIS algorithm.","PeriodicalId":34935,"journal":{"name":"Australian Journal of Electrical and Electronics Engineering","volume":"17 1","pages":"261 - 269"},"PeriodicalIF":0.0,"publicationDate":"2022-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84060329","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}

These converters are based on the use of semiconductor switching components that generate rapid voltage (dV/dt) and/or current (dI/dt) variations. This can result in electromagnetic disturbances that must be minimised in order to respect electromagnetic compatibility standards. Compliance with standards is often achieved by adding a heavy and bulky filter to the system. In order to optimise the EMC aspects, it is interesting to take into account the EMC constraint from the design phase, in order to do so, a predictive study of these disturbances must be available. In this work, the origins of electromagnetic disturbances created by a series chopper are presented.

Harmonic injections beyond certain limits introduce some negative effects such as malfunctioning of protective devices, reducing power system reliability. Therefore, its analysis is one of the most important aspects for the safe and reliable operation of the modern distribution system. For this, analysis of harmonic behaviour at PCC under different PV penetration levels is carried out to establish the relationship between them. Several measurements have been taken at PCC with varying PV penetration in a 3 MW ground-mounted solar PV plant at Aligarh Muslim University, Aligarh, India. These measurements include harmonic components of voltage and current by using a fluke II power quality analyser, and the results are compared with the limits imposed by the standards.","PeriodicalId":34935,"journal":{"name":"Australian Journal of Electrical and Electronics Engineering","volume":"123 36","pages":"283 - 293"},"PeriodicalIF":0.0,"publicationDate":"2022-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72376662","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}
