Βαμβακάρος, Δημήτριος/ Vamvakaros, Dimitrios

This work focuses on the development and construction of a power supply, capable of providing symmetrical voltage from 0 to 25V. The importance of such a power supply is fundamental to the proper functioning of various electronic systems, as it is the main source of energy for powering circuits and devices. First, the paper offers an extensive review of the history of electronic science, presenting its evolution from an tiquity to modern applications. Special emphasis is placed on the fundamentals of electronics, such as electric current, frequency, and basic electronic components. The functional characteristics, structure and practical applications of diodes, transistors , operational amplifiers and transformers are analyzed in detail. The paper then examines electronic signals and oscillators, identifying the different kinds of signals and their applications. Here is a thorough analysis of signal generators, including the ir types, functions, and requirements. Special emphasis is given to frequency generators and their applications in electronics. The paper proceeds with a review of batteries and power systems, examining their historical development and their importance in modern electronics. In particular, the structure and operation of power supply systems are analyzed, including the transformer, rectifier, stabilizer and control circuits. The construction steps, the selection and connection of the components, as well as the necessary tests to verify the functionality of the system are then presented in detail. Analysis of transformer, voltage rectification, stabilization and control circuits is included. In conclusion, the work points out the advantages and improvement p ossibilities of the fabricated power supply. The test results demonstrate the effectiveness and reliability of the system, while improvements are suggested for future research and reliability of the system, while improvements are suggested for future research and development.development
