Desenvolvimento de um circuito de carga eletrônica para uso em laboratório

Abstract

During their undergraduate studies, students can choose to participate in scientific initiation activities, which are essential for complementing the teaching process. In activities developed by students in courses such as Electrical Engineering, the use of the laboratory environment and its equipment is often necessary. One piece of equipment that can be very useful in the laboratory for electrical testing is the programmable electronic load, which exists in various models on the market, but at high costs. This work proposes the creation of an electronic load with low-cost equipment, taking advantage of a previously proposed work, which operates in various modes and can also extract the characteristic curve of a photovoltaic panel. Control and data acquisition are done using a microcontroller, and the load can be configured via a Python interface on the computer, withWi-Fi communication. The work presents the circuit development, the prototyping process, and the analysis of the results, presenting its limitations and also relevant contributions for future work.
