摘要
Silicon carbide (SiC) power MOSFETs are characterised by potentially thermally unstable behaviour over a broad range of bias conditions. In the past, such behaviour has been shown for silicon (Si) MOSFETs to be related to a reduction of Safe Operating Area at higher drain-source bias voltages. For SiC MOSFETs no characterisation exists yet. This paper presents a thorough experimental investigation for devices of different voltage classes (600 and 1200 V) and different manufacturers, highlighting important differences in electro-thermal performance and failure mode as compared to Si devices. The goal is to derive information for design optimisation and reliable device development for a diverse range of target applications. (C) 2012 Elsevier Ltd. All rights reserved.
