ANÁLISE E SIMULAÇÃO DE UM ESTÁGIO CONVERSOR ENTRELAÇADO PARA O CARREGAMENTO DE BATERIAS

Abstract

Faced with the global challenge of decarbonizing the transport sector, driven by climate commitments such as the Paris Agreement and the National Policy on Climate Change, electric vehicles (EVs) emerge as a crucial alternative. However, the technical and economic viability of this transition critically depends on the development of efficient and reliable charging infrastructure. This work addresses this problem through the analysis and simulation of a two-phase interleaved Buck converter for Level 2 EV chargers. Designed to operate at 7.5 kW, the converter was modeled in MATLAB/Simulink with two current control strategies - global and cell-based - aiming to overcome the challenges of efficiency, thermal distribution, and power quality inherent to high-current chargers. The results demonstrated that the interleaved topology, combined with cell control, provides precise output current regulation at 18 A with reduced ripple, optimized transient response, and better loss distribution, validating its application as a technological solution for charging infrastructures that combine performance, reliability, and contribution to sustainable mobility.
