To define the best of all these concepts, a literature review was carried out, defining the equipment's design parameters leaving in count its critical points. The equipment was designed in 3 steps, which consist the initial mathematical calculations for the chosen topology and subsequent computational validation using the PSIM software. Conclusively, the purposed system is assembled and the physical results are discussed, adopting as basis the comparison between the calculated values and those obtained by using the oscilloscope, showing a good convergence of the project regarding the initial objectives.pt-BREngenharia ElétricaFonte chaveadaFlybackTrabalho de Conclusão de Curso
