摘要：

The present work aims to evaluate several classical topologies of a 10kW single-phase converter for hybrid AC-DC microgrids considering cost and efficiency. The main objective is to evaluate the optimal configuration of a two-stage interlinking converter for a microgrid with 220V AC and 380V DC buses. To define this solution, a set of 384 combinations of converter topologies and power switch technologies (Si IGBT and SiC MOSFET) were considered. The PSIM Thermal Module was used to estimate the power switch losses for each configuration and a MATLAB inductor sizing routine was built to design the magnetization and obtain the power losses. Through Pareto Boundary analysis it was possible to observe optimal solutions using full-IGBT, full-SiC and hybrid converters, where the combination of Full-Bridge/Half-Bridge topologies had the best cost vs. efficiency ratio.
