The main aim of this project is to assess the lifecycle emission, quality and reliability of a DC-DC converter, considering various topologies and semiconductor devices such as MOSFET, IGBT in such designs. A MATLAB based model to answer the hypothesis of an optimized design will also be developed. Different end of life scenarios for power electronics components will be considered and specific tests will be proposed to investigate the end of life of power electronics components.
