DISEÑO DE UNA FUENTE DE ALIMENTACIÓN DE DOS ETAPAS: AC-DC CON CORRECCIÓN DE FACTOR DE POTENCIA Y DC-DC CON UN CONEVERTIDOR DIRECTO CON FIJACIÓN ACTIVA DE TENSIÓN (ACTIVE-CLAMP FORWARD CONVERTER) E IMPLEMENTACIÓN DE SU ETAPA AC-DC

Abstract

The main objective of this project from the Graduation Subject "Switching-mode Power Supplies" (Power Supplies Switch Mode) is to design a power supply with two stages: AC-DC with a Boost converter and DC-DC with an Active Clamp Forward converter ACFC . For the design of the AC-DC converter stage a Boost type topology is used, the components are dimensioned based on current and voltage specifications and similarly identification systems for the controllers design was used. For the DC-DC converter stage an Active Direct voltage clamp is used, the components are dimensioned but not implemented in physical; to meet the objective set we use simulation tools such as Matlab, Simulink and SIMpower Systems and Proteus for the design of printed circuit boards. Finally, the AC-DC stage is implemented, which consists of the boost converter, and it’s done to acknowledge and compare simulation results with those obtained by experimental mean.
