This research article discusses a new low-power circuit design\u0000 the approach of FORTRAN (FORced stack sleep TRANsistor), which decreases the\u0000 leakage power efficiency in the CMOS-based circuit outline in VLSI domain.\u0000 FORTRAN approach reduces leakage current in both active as well as standby\u0000 modes of operation. Furthermore, it is not time intensive when the circuit\u0000 goes from active mode to standby mode and vice-versa. To validate the\u0000 proposed design approach, experiments are conducted in the Tanner EDA tool\u0000 of mentor graphics bundle on projected circuit designs for the full adder, a\u0000 chain of 4-inverters, and 4- bit multiplier designs utilizing 180nm, 130nm,\u0000 and 90nm TSMC technology node. The outcomes obtained show the result of a\u0000 95-98% vital reduction in leakage power as well as a 15-20% reduction in\u0000 dynamic power with a minor increase in delay.

In the following paper, a fuzzy\u0000 evolutionary algorithm is combined with a proportional-integral-derivative\u0000 (PID) controller to control the speed of a PMSM. In this structure, to\u0000 overcome the PMSM challenges, including nonlinear nature, cross-coupling,\u0000 air gap flux, and cogging torque in operation, a Takagi-Sugeno fuzzy\u0000 logic-PID (TSFL-PID) controller is designed. Additionally, the particle\u0000 swarm optimization (PSO) algorithm is developed to optimize the membership\u0000 functions' parameters and rule bases of the fuzzy logic PID controller. For\u0000 evaluating the proposed controller's performance, the genetic algorithm\u0000 (GA), as another evolutionary algorithm, is incorporated into the fuzzy PID\u0000 controller. The results of the speed control of PMSM are compared.

Harmonic cancellation of\u0000 distribution network is currently a serious problem, especially in high\u0000 electrical industry. The main source of harmonic currents injected into the\u0000 network requires attention to reduce the current harmonic levels. Energy\u0000 quality is a fairly broad concept which covers both, the quality of power\u0000 supply (voltage wave) and these of the currents injected into the electrical\u0000 grid. In this context, a modern approved preventive solution in purpose to\u0000 limit the rate of harmonic disturbance caused by the deferent power\u0000 electronics systems connected to the grid must take action. It appears\u0000 necessary to develop the quality and stability of the grid and develop\u0000 curative devices such as converters provided with a control device making\u0000 the current drawn on the most sinusoidal network possible. This paper\u0000 proposes a control of tow stage grid tied PV system established on finite\u0000 set model predictive control (FS-MPC). The design of FS-MPC is developed\u0000 depending on the structure and operating principle associated to three-phase\u0000 inverter tied to the grid. In this context, we have also employed the\u0000 structure of MPPT controller (P&O) and PI controller for adjustment of the\u0000 DC-bus voltage. To set the proposed control scheme, numerical simulations\u0000 are carried out using Matlab/Simulink 2013b. The obtained results\u0000 demonstrate that the proposed control scheme assure the tracking of MPP and\u0000 the injection of extracted PV power into the grid with high current quality\u0000 under irradiation changes.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"13 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86625476","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}
