Quality Assessment and Reliability Analysis of Semiconductor Power Modules

Lead Research Organisation: University of Nottingham
Department Name: Faculty of Engineering

Abstract

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. Lifecycle assessment of components and comverters will be done using special LCA software like Gabi or Simapro. At the end of research, a new prototype of DC-DC converter with new topologies and specific semiconductor components to ensure optimal sustainability, reliability and quality will be produced. Y1: Undertaking taught modules in Newcastle university and Nottingham university to gain some practical knowledge and understanding of power electronics (especially the various types of DC-DC converters) and also experience in the design, simulation, life cycle assessment, construction and testing of a power converter.

Key Milestone: Successful completion of selected modules and familiarity with various simulation software such as PSIM, Simulink, PLECS, Gabi etc. Also good exposure to electronic components such as MOSFET,IGBT, Resistors, Inductors, Capacitors, Diodes and the purposes they serve in power converters.
