Abstract:
Silicon Carbide (SiC) MOSFETs offer increased switching speeds, reduced filtering requirements and lower switching losses when compared to Silicon IGBTs in power-converters. SiC MOSFETs have disrupted the power-semiconductor market at lower power-ratings of 20-200 kW, and are now commonly used in electrical vehicle applications. Devices with current ratings approaching the kiloamp region are now becoming available, meaning a pathway for SiC MOSFETs to continue displacing IGBTs up the power chain to applications such as traction and renewables now exists. This talk will discuss the work of the Power-Electronics team at Edinburgh, where we have focused on some of the challenges associated with implementing Megawatt scale SiC MOSFET converters, including: busbar design for minimisation of commutation loop inductance; Effective parallel connection of modules to scale the switching performance achievable with lower-current devices to kiloamp scale, while also reducing voltage overshoots and oscillatory switching behaviour; and active gate-driving techniques to mitigate overshoots and oscillatory switching at source, with minimal impact on switching energy loss.

Biography:
Paul Judge is currently a Reader at The University of Edinburgh and Royal Society Industry Fellow. He received the B.Eng. degree in electrical engineering from University College Dublin in 2012 and the Ph.D. degree from the Department of Electrical and Electronic Engineering, Imperial College London, in 2016. His research interests include power converter design and control, as well as power system integration aspects of renewable energy technology. He leads a team of 5 PhD students and two Post-Doctoral Researchers, with a strong experimental focus on next generation power-converter design. He is currently leading an industry funded research project on Silicon Carbide converter design, as well as leading work-packages in the EPSRC funded Wind2DC project and the Innovate UK funded Network-DC project. He is a co-Director of the EPSRC Net-Zero Enabling Electrical Engineering (N-ZEEE) network, which aims to build a critical mass of researchers in the Power-Electronics Machines and Drives (PEMD) research sphere.
