Objectives
Abstract This project proposes a paradigm shift in the operational management and use of power converters that entails active reliability management. This involves predicting failure and managing the remaining useable life of the power converter. Power electronic converters are indispensable to modern civilisation. They are responsible for electrical power conversion for a range of applications that span the few watts for portable hand-held electronics to several gigawatts for entire electrical power networks. Over the past few decades, the need for industrial decarbonisation has intensified the research into more efficient and reliable power electronic devices, components and converters. This is because power electronic converters are required for integrating renewable energy sources (solar, wind, tidal etc.) into the electrical system. Furthermore, electric transportation, which is seen as critical for reducing green-house emissions, relies very heavily on power electronics. Hybrid and full electric vehicles require power converters to control the traction machine, likewise, electric trains require power converters. Marine propulsion has also adopted the electric paradigm with the gas driven turbine replaced by a converter driven electrical motor. However, as power converters are driven at increasingly higher power densities, several reliability concerns have been recognised. The power converters are comprised of power modules, which in turn are comprised of switching power semiconductor devices in an electrically isolating but thermally conducting package. The reliability of the power semiconductor device and its mechanical interconnects has been intensely investigated by industrial and academic researchers over the last decade. Silicon devices have been the principal technology in power electronics for the last few decades however, silicon carbide and gallium nitride devices have emerged as viable alternatives. These new devices are referred to as wide bandgap devices because they have energy bandgaps larger than that of silicon. The simply means that they can withstand more energy thereby increasing the efficiency of power conversion. The reliability of these WBG semiconductors is increasingly becoming a very important topic since these new devices are gaining increasing market penetration. In applications with high failure costs, for example, automotive traction, aerospace and grid connected converters, the uptake of new technology is slow. By developing technologies that can improve the reliability of these new devices and monitor their health on-line, the uptake of new WBG power modules is very significantly de-risked. This project aims to do just this, by providing a condition monitoring and health management platform for WBG based power electronic modules
