Diseño de una Fuente de Alimentación de Dos Etapas: AC-DC con Corrección de Factor de Potencia y DC-DC con un Convertidor Directo de Dos Conmutadores (Two-Switch Forward Converter) e Implementación de su Etapa AC-DC

Abstract

The present work is about the design of a Two Stage Switching Mode Power Supply, which consist on a PFC (Power Factor Correction) based on a Boost converter and a Two-Switch Forward Converter. Doing the respective theoretical calculations of the system design and control of both stages to demonstrate later through simulations the proper functioning, it has to be taken into account that the implementation of the controllers is going to be made using an IC (integrated circuit) that simplifies controllers in only one chip, saving space on the board in this way. Finally, the implementation of the first stage of the source is made on a double sided PCB (printed circuit board), and is verified that the resulting values clearly match the respective simulations.
