The fundamental research activities of the PERL team aim at pushing the limits of power electronic converters in terms of their switching frequencies. Applications span various industries where small size, low weight and high efficiency are beneficial.
Graz University of Technology (TU Graz) and Silicon Austria Labs (SAL) have launched their new joint power electronics research laboratory "PERL". PERL is dedicated to advancing fundamental research in a strategic and innovative topic, i.e., the high frequency switched power converters, with the aim of preparing researchers for future industry challenges.The increase of the operating switching frequencies of power electronic converters allows to build them with higher performance and power densities with respect to traditional silicon-based solutions.
The fundamental research activities of PERL aim at exploring the limitations when pushing the switching frequency of power electronic converters and to work on solutions to overcome these limitations. The research work aims to beneficially use the superior properties of wide bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), by proposing and studying new power conversion topologies (with a strong focus on soft switching ones), optimal usage and design of passive components, novel gate driving solutions, and smart packaging and integration techniques. The main objective is to push the operating frequency of the converters and to explore and understand the associated limitations, also considering the electromagnetic interference in the analysis.
The PERL Lab is led by Michael Hartmann, Professor and Head of the Electric Drives and Power Electronic Systems Institute (EALS) at TU Graz, and Roberto Petrella, Staff Scientist in Power Electronics at SAL and Professor at the University of Udine in Italy.
Researchers from both TU Graz and SAL will work together, including four dedicated PhD students. The joint laboratory is initially planned to run for three years.
