SuperGrid Institute’s participation at AGP21

2019-07-26T09:39:56+02:00June 27th, 2019|All, Conference, Event|

The Association Grand Projects 21 – Major Programmes and Projects for the 21st Century (AGP21) met this Thursday in Versailles to discuss the development of interconnected electricity networks on a global scale. SuperGrid Institute was invited to present its vision and discuss the appeal of multi-terminal HVDC technologies in the design and construction of future energy highways. The subsea node concept developed at SuperGrid Institute was also introduced as an essential building block for extending offshore networks and integrating renewable energies on a wide-scale.

Measurement and Analysis of SiC-MOSFET threshold voltage shift

2019-07-26T09:41:02+02:00October 4th, 2018|Conference, Power Electronics & Converters|

Gate-oxide technology weakness is a main reliability issue of Silicon Carbide MOSFET transistors. The threshold voltage shift is a critical phenomenon that addresses the reliability of industrial power applications. It is important to have a better understanding of the phenomena implied in the gate threshold voltage shift. In this context, HTGB test is proposed and the resulting gate oxide stress is studied and discussed in this paper.

Repetitive short-circuit measurement on SiC MOSFET

In the future, Medium Frequency Transformers (MFT with a frequency range 5 kHz to 100 kHz) will be major components in DC-DC converter applications, for both Medium Voltage Direct Current (MVDC) and High Voltage Direct Current (HVDC) networks. Importantly, the corresponding power losses should be accurately calculated in order to reach performance targets (very high efficiency).
