Resumo
The performance of single-phase inverter topologies in relation to their power density and efficiency is investigated in this dissertation. The main objective is to assess the competitive advantages among topologies and determine which one is more viable for implementation in photovoltaic energy applications. In this work, a brute force multi-objective algorithm is implemented to generate various inverter designs for each topology, creating a solution space. Optimization using the Pareto-front technique selects optimal designs for comparison with the topologies under study. Unlike many studies found in the literature, this multi-objective algorithm uses a database of real components and their datasheet information instead of industry average metrics, hence the outcome of the design algorithm relates to an actual implementation of the converter structure, therefore the performance indexes refer to a real system rather than a theoretical industry boundary. Finally, this multi-objective study takes into account the design of each electronic, magnetic, and heatsink device, where each topology can provide a more optimal solution space than another topology.
