Study and assessment of technical and commercial feasibility of a new Silicon Carbide (SiC) Bipolar Junction Transistor (BJT) technology for High Voltage DC (HVDC) electricity transmission for offshore renewables

该项目旨在研究和评估用于海上可再生能源高压直流输电的大型电力电子逆变器的新型碳化硅（SiC）双极结型晶体管（BJT）技术的技术和商业可行性。这项新技术在可靠性和效率方面有了实质性的提高，并降低了SiC BJT功率半导体器件的制造成本，使HVDC电网的应用更加广泛;与现有的硅（Si）基HVDC逆变器相比，它的开发可以将海上风电的平准化能源成本（LCOE）降低5.3%。

The project aims to study and assess the technical and commercial feasibility of a new Silicon Carbide (SiC) Bipolar Junction Transistor (BJT) technology for large-scale power electronics inverters used in High Voltage DC (HVDC) electricity transmission for offshore renewables. The new technology offers substantial improvement in reliability and efficiency and reduction in manufacturing cost of SiC BJT power semiconductor devices, enabling more widespread application of HVDC grids; its exploitation can potentially reduce the Levelised Cost of Energy (LCOE) from offshore wind by 5.3% when compared to existing Silicon (Si) based HVDC inverters.
