Análise e controle de um sistema de conversão de energia para carregamento de veículos elétricos

Abstract

This work aims to present an analysis and control of an energy conversion system for an integrated converter for charging electric vehicles, which supplies energy in the form of AC to the electric vehicle. This charging mode is widely used by electric vehicle owners in their homes. First, a PWM rectifier is modeled by state space in synchronous coordinates, to obtain a model that relates input currents to the DC bus voltage and a second model through the dynamic power balance equation of the circuit. Afterwards, a modeling of the buck converter is performed using its medium circuit model. These models are used to carry out the designs of the control loops, which were made using the proportional-integral drivers. These calculations are carried out in order to obtain the energy storage elements of the system. Finally, simulation results are required for the operation of the energy conversion system.
