(2023-08-26) Lopes, Brenda da Silva; Souza, José Geraldo de Pontes e; http://lattes.cnpq.br/3583358046117558; Souza, José Geraldo de Pontes e; http://lattes.cnpq.br/3583358046117558; Cordeiro, Celso Souza; http://lattes.cnpq.br/4969144304480235; Ribeiro, Laura Michaella Batista; http://lattes.cnpq.br/8632002394782219
Physics is the science dedicated to researching and analyzing natural phenomena such as acoustics, optics, dynamics and electricity. Training in this area provides knowledge to understand the relationship between energy and matter in different dimensions, from atomic particles to the Solar System. Based on the applied studies, the beginning of research on temperature was chosen, then choosing applications on Peltier Tablets, which are devices based on the Peltier effect and are applied to produce a cooling or heating effect. This work addresses concepts involved in the operation of these devices such as: history of the Peltier effect and development of Peltier effect plates. A study is made based on the graphical and practical results. For this, a “mini refrigerator” refrigeration structure is implemented and measurements are made to determine the efficiency of the system. Finally, conclusions are presented about the study developed.

Knowledge of transistors is of paramount importance for the student of electronics. The objective of this work is to make the electrical characterization of the Mosfet transistor. This is bibliographical research and the use of measuring instruments from the IFAM-CMDI laboratories, information on their operation will be collected such as voltage, current and characteristic curve, for which a simple circuit will be mounted on a protoboard. After collecting the voltage and current measurements of the Mosfet transistor, these data will be inserted into the MultiSim simulator. The results of the electrical measurements on the breadboard and the MultiSim simulator will be compared with the Mosfet 2N7000 transistor datasheet. It was possible to conclude that the results obtained from electrical measurements of voltage, current and characteristic curve of the 2N7000 transistor are close to the values in the datasheet of said transistor.

The present work presents the creation and analysis of a class D amplifier, to carry out the amplification, the integrated circuit IRS2092 from IOR - Infineon Technologies was used, capable of managing, modulating and amplifying the signals, requiring only a good choice of power and monitoring components. it also requires a good selection of switching transistors and a suitable passive filter for demodulation. Thus, an amplifier capable of delivering a power of 40W in a resistive load with low harmonic distortion, less than 0.8%, was designed, being comparable to linear amplifiers, but with an efficiency greater than 90%, common value for class amplifiers D .In the work, the values of the components that fit in the test sequences are calculated. To arrive at the results, a synthesis of the functioning of each amplifier stage was made using commercially components, using an automatic oscillating modulation that has an excellent sound quality, besides making the circuit smaller within its cost. Finally, the amplifier was assembled to carry out the specifications and tests in order to validate the operation and practical specifications.

With the growing demand for electricity and its generation inefficiently, our planet is undergoing severe climate-environmental changes. In order to ease this almost irreversible situation, it is becoming increasingly feasible to explore clean energy forms, that is, without emission of pollutants, such as solar photovoltaic energy. The work to be presented explores this type of energy that has as a source the solar star (sun), purely renewable and available for its use. A study is presented for the technical feasibility of a photovoltaic system connected to the network for deployment in the Campus Distrito Industrial of the Federal Institute of Education, Science and Technology of Amazonas

This project aims to implement a helmet alert system for motorcyclists with hearing impairment. Basic concepts of electronic and complex circuits based on ESP32 will be presented, accompanied by studies on Assistive Technology, how it has been developed over the years, as well as the types of communication made by electronic components and the most used ways for reading blind spot objects through books, websites and tutorials. Thus, it is intended to build a practical and dynamic project, which the user feels comfortable carrying as if he were wearing any helmet, in addition to the social inclusion of people with hearing impairment, ensuring a greater sense of security and improving perception of vehicle positioning.
