Projeto de uma fonte de tensão senoidal estabilizada com entrada com correção de fator de potência

Abstract

This work presents the design and development of a 1 kW stabilized sinusoidal voltage source with power factor correction input with the objective of delivering a voltage of 120 V and 60 Hz at its output while considering input voltage within the range of 90 V to 240 V. To do this, it is necessary to design two circuits and their respective control systems. The first circuit designed is a power factor compensator based on the full-wave rectifier and boost converter with its current and voltage loop controllers. The second designed circuit is a full-bridge voltage inverter with its control system. MATLAB/Simulink 2022a softwareis used to implement and simulate the circuits and their controllers. Tests are carried out with different input voltages within the converter’s working range, as well as simulations are carried out for atypical conditions in order to verify the functionality of the project.
