Software para projeto e análise de conversores estáticos

Abstract

This paper presents the development of a tool to assist in the design and analysis of simple static converters such as buck, boost, buck-boost converter for both operation modes and flyback for DCM. Initially, a bibliographic review about power electronics and the use of software in education is presented. Subsequently, the proposal and the project development are presented. The tool was programmed in VBA language through Microsoft Excel spreadsheet platform. The tool provides design results such as duty cycle, load, output current, voltage and current graphs on all components, and indicate relevant semiconductor switch and diode models for the project. To assess the tool’s viability and highlight which points needed to be improved, a test was conducted with students from Electrical Engineering subjects. From the results, quality tools were applied to find the main points that should be improved and a list of priority actions was proposed to ensure continuous improvement of the project.
