EPE Paper – Measurement of WBG-based power supplies
This paper discusses different measurement methods to evaluate the efficiency of WBG-based power supply solutions, including electrical measurement methods and their verification with calorimetric methods, and compares the performance of Si-based and GaN-based chargers.
EPE Paper – Looking beyond energy efficiency – Environmental aspects and impacts of WBG devices and applications over their life cycle
The environmental aspects and impacts of wide bandgap (WBG) materials such as Silicon Carbide (SiC) and Gallium Nitride (GaN) in specific end-use electronic applications and products have not yet been fully investigated. The design trade-offs and comparison of WBG with classic Silicon based technology for the same applications, with a life cycle thinking perspective, are only starting to emerge.
EPE Paper – Application Readiness Map for WBG-Semiconductor-Based Applications
The Power Electronic Conversion Technology Annex (PECTA) application readiness map for Wide bandgap (WBG) semiconductors describes their expected market position up to 2035. It is based on interviews with many experts and different roadmaps and could be used as one basis to decide which power semiconductor technology to choose. This paper presents an updated version and the underlying assumptions.
Design Aspects and Environmental Impacts of Wide Band Gap Based Semiconductor Technology in Chargers for Electronic Devices
This paper presents the outcomes of the work from PECTA Task B, Energy and environmental related Life Cycle Assessment, conducted between January 2022 and February 2023. See
A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors
Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is
