Abstract

Given the recent push towards the next-generation wide band-gap semiconductor devices, electromagnetic interference is a growing concern due to the higher switching frequencies, voltages and currents. Therefore, understanding the electromagnetic behaviour of power electronic systems is important. Visualising the real-time thermal dynamics of these systems is possible using infrared imaging cameras. However, no equivalent tool exists for the real-time prediction of electromagnetic fields.

This is due to the computational complexity of electromagnetic problems which typically makes them too slow to model in real-time. By implementing a number of techniques to accelerate this process, the simulation time can be significantly reduced, allowing the electromagnetic dynamics of a system to be predicted in real-time.

This thesis explores how real-time simulation models and extended reality technologies can be used to replicate the thermal-imaging effect but for electromagnetics. An innovative augmented reality application is developed allowing the 3D visualisation of electromagnetic effects overlaid on the physical device in real-time.
