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

Abstract

This document shows the design of a switching mode power supply with two stages, the first stage is a circuit for power factor correction based on a boost converter and the second stage of an isolated converter circuit based on a Forward converter to obtain a DC output with low voltage and current ripples. The main objective is about to analyze the operation of switching-mode power supplies and be able to design and implement them. The design is divided into two parts: power and control stage. The power stage focuses on the parameters of voltage and current that the source handles as input and output, while the control stage design focuses on the behavior of the output according changes and perturbations it could get. The technique used in the design the control stage is the K Factor Method that allows us to find poles and zeros for a phase margin and crossover frequency given; the two stages use its respective controller for voltage and current.
