Advanced Design Tools and Modeling for Power Electronics Integration and Reliability

Dr. Hua Lu from the Department of Mathematical Science at the University of Greenwich presents innovative methodologies in the design and modeling of power electronics. Focusing on electro-thermal management and reliability, the project aims to develop compact dynamic models for thermal analysis and embed them into multi-objective optimization frameworks. Key objectives include creating high-fidelity finite element models and reduced-order equivalents, integrating design variations into reliability predictions, and ensuring the practical application of these tools within the power electronics community.

  1. Underpinning Power Electronics Component Integration Theme WP 4: Design Tools and Modelling Dr Hua Lu Department of Mathematical Science University of Greenwich Email: H.Lu@gre.ac.uk Research Interests: Computational Science, Reliability analysis and optimization, Design tools for power electronics

  2. Project Plans & Objectives Design for Electro-Thermal Management Develop a methodology for generating dynamic electro-thermal compact models that can be used in a high fidelity thermal analysis Develop a methodology to embed these models within a multi-objective optimisation framework Design for Reliability and Robustness Develop high fidelity finite element models for relevant component structures in this theme Develop reduced order model equivalents of the above for fast analysis Develop physics-of-failure lifetime models for failures relevant to structures developed in this WP Identify a methodology to include design/manufacturing variation within the reliability predictions Identify approach to embed the above within a multi-objective optimisation framework such as PowerLife
