It is the most rigid and thinnest\u0000 material ever discovered and has a wide range of uses regarding its unique\u0000 characteristics. It is expected that this material will create a revolution\u0000 in the electronics industry. Graphene is a very powerful superconductor as\u0000 the movability of charged particles is high on it, and additionally, because\u0000 of the high surface energy and ? electrons being free, graphene can be used\u0000 in manufacturing many electronics devices. In this paper, the applications\u0000 of graphene nanoparticles reinforced polymer nanocomposites in the computer\u0000 and electronics industry are investigated. These nanoparticles have received\u0000 much attention from researchers and craftsmen, because graphene has unique\u0000 thermal, electrical and mechanical properties. Its use as a filler in very\u0000 small quantities substantially enhances the properties of nanocomposites.\u0000 There are various methods for producing graphene-reinforced polymer\u0000 nanocomposites. These methods affect the amount of graphene dispersion\u0000 within the polymer substrate and the final properties of the composite. The\u0000 application and the properties of graphene-reinforced polymer nanocomposites\u0000 are discussed along with examples of results published in the papers. To\u0000 better understand such materials, the applications of these nanocomposites\u0000 have been investigated in a variety of fields, including batteries,\u0000 capacitors, sensors, solar cells, etc., and the barriers to the growth and\u0000 development of these materials application as suggested by the researchers\u0000 are discussed. As the use of these nanocomposites is developing and many\u0000 researchers are interested in working on it, the need to study and deal with\u0000 these substances is increasingly felt.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"53 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88112704","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}

In the conventional direct torque control (DTC) of a permanent\u0000 magnet synchronous motor (PMSM), hysteresis controllers are used to choose\u0000 the proper voltage vector resulting in large torque ripples. The direct\u0000 torque control can accelerate the torque responses but increases the torque\u0000 ripple at same time. Nowadays, exist some other alternative approaches to\u0000 reduce the torque ripples based on (Predictive SVM) technique. This method\u0000 is based on the replacement of hysteresis comparators (used in conventional\u0000 DTC) by Proportional Integral (PI) regulators and the selection table by\u0000 space vector modulation (SVM). The simulation results confirm that this\u0000 proposed method where the control of the switching frequency is well\u0000 controlled, allows us to reduce the oscillations of the electromagnetic\u0000 torque and flux by 20 % and 30%, respectively with a good dynamic response\u0000 compared with conventional DTC.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"53 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2020-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90468354","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\u0000 simulation result shows the delay of the CICSI delay block is 592ps.
