EPE Paper – Identifying the potential of SiC technology for PV inverters

Silicon Carbide (SiC) devices offer energy efficiency improvements over conventional silicon (Si) semiconductors. Through measurements and simulation results, this paper intends to quantify this efficiency improvement in a typical photovoltaic (PV) application. This allows designers and policy makers to better understand the benefits of SiC, enabling more informed decisions.

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.
