Project abstract

This project aims to investigate possibilities/challenges/requirements of high voltage (>10kV) SiC semiconductor devices for high power applications. The promising material properties of SiC as semiconductor material gives superior operating performance in comparison to Si (e.g., higher blocking voltage capability, operated at higher switching frequencies and at higher temperatures) which may offer system level benefits such as reduced number of devices/cells, less complex system and reduced cooling requirement and station foot-print. Accurate device simulation studies are required to predict the performance of these high voltage SiC devices and to extract the static and dynamic characteristics in a wide operating range. The project outcome may serve as input in power electronic converter cell/system design, in HVDC, FACTS and other high power applications.


Summary of work

2015. At this point, a literature study is carried out to cover the current status of the SiC semiconductor device research field and to identify challenges and research opportunities of different HV SiC device concepts, for instance, series/parallel/matrix configurations of multiple medium voltage devices, large wafer area devices and hybrid device solutions.

2016. The results of the first work package were finalized and presented at WiPDA2016 (4th IEEE Workshop on Wide Bandgap Power Devices and Applications). Within this study, the theoretical performance of ultra-high voltage SiC devices (SiC MOSFET, SiC IGBT and SiC GTO) were investigated. The conduction power loss and switching power loss were predicted and compared with different modelling approaches, for SiC MOSFETs up to 20 kV and SiC GTO thyristors and SiC IGBTs up to 50 kV.

2017. The second work package, about experimental characterization of 10 kV 100 A SiC MOSFET power modules, covering measurements of the static characteristics (i.e., I-V, C-V, body diode, leakage current and blocking voltage characteristics) and dynamic characteristics (i.e., switching transients, switching losses and short-circuit characteristics), are published in IEEE Transactions on Power Electronics.

2018. The Technology CAD (TCAD) finite-element simulation model has been calibrated and verified against experimental data of a 15 kV silicon carbide (SiC) bipolar junction transistor (BJT). The device structure of the high voltage BJT has been implemented in the Synopsys Sentaurus TCAD simulation platform and design of experiment simulations have been performed to extract and fine-tune device parameters and 4H-SiC material parameters to accurately reflect the 15 kV SiC BJT experimental results. The findings are presented at the ECSCRM2018 (European Conference on Silicon Carbide and Related Materials) conference.

2019-2020. Work related to TCAD simulations of high voltage bipolar SiC devices: An IGBT model in TCAD was calibrated against previously reported experimental data which was then used to predict the static and dynamic performance in ultrahigh voltage SiC IGBTs. The findings were presented in the ICSCRM conference (Kyoto) and in one journal paper (IEEE Transaction on Power Electronics).

2020-2021. The work related to junction termination structures in ultrahigh-voltage devices is summarized in a journal paper (IEEE Open Journal of Power Electronics). In this work, the JTE length requirements, design guide lines, and active area ratios for 20-50 kV devices are presented. The dynamic avalanche and current filamentation onset limits for high voltage SiC diodes are investigated by TCAD simulations. The findings are presented in IEEE Journal of Emerging and Selected Topics in Power Electronics. The ultrahigh-voltage (20-50kV) SiC GTO thyristor performance are assessed and compared to ultrahigh-voltage SiC IGBTs and state-of-the-art Si BIGTs, employed in a high-power MMC-based HVDC application example. The modeling approach and simulation results are presented in IEEE Transactions on Power Electronics. The PhD thesis was written and defended during spring 2021.
