Resumo
This dissertation addressed the development of a solution for ultra-fast charging of electric vehicles (XFC), through a structure based on Partial Power Processing (PPP), which integrates two converters: the bidirectional resonant CLLLC and the three-phase interleaver. Model-Based Predictive Control (MPC), combined with the application of the Back-EMF theory, was implemented as a central control strategy in both topologies. The proposed system demonstrated high efficiency, good dynamic performance. The modular and bidirectional architecture, operating at high frequency, proved to be adequate to the demands of the XFC, contributing to the reduction of losses and improvement of the reliability of the system. The proposal is thus configured as a promising and scalable alternative for future electric vehicle charging stations with high power and performance requirements
