Modelling of Power Modules for lifetime, accelerated testing, reliability and risk

Lead Participant: Semelab Limited


We propose to develop and exploit virtual reliability models to simulate operation wear out and failure mechanisms in electronic power modules. These devices underpin a broad range of applications in automotive, aerospace, traction and power distribution systems. Environmental legislation is forcing the development of new systems to reduce noise and harmful emissions. This requires development of next generation power modules. Testing and qualification of these devices is expensive and time-consuming. New integrated virtual reliability models are needed to identify potential problems early in the design stage to improve reliability, reduce time to market and drive down overall device cost, thereby improving the UK''s industrial competitiveness. The consortium brings together a diverse industrial base to lever expertise in modelling, design, testing and manufacturing which is required to enable the development of this complex design tool.
