This project is a collaboration between Zagres Limited and Cambridge University Engineering Department (CUED) andaims to study, prove and quantify the performance and economics of a newly developed Silicon Carbide Bipolar JunctionTransistor (SiC BJT) technology through building and testing a prototype 50 kVA SiC BJT inverter as a building block forHigh Voltage Direct Current (HVDC) transmission applications. The SiC BJT power module technology has voltage,frequency and thermal ratings substantially greater than existing Si-based modules, which can significantly reduce size andenhance reliability and efficiency of power electronics inverters. These benefits will contribute to reducing the cost ofenergy for offshore renewables.The 50 kVA SiC BJT inverter will be the first of its kind and will act as a stepping-stone to develop and industrialise largescaleHVDC SiC-based inverters. The performance and benefits of the inverter will be assessed and compared to existingcommercial Si-based solutions. In addition, a thorough business plan and exploitation model will be developed to supportthe follow-on commercialisation.This project aims to prove and quantify the benefits and economics of the SiC BJT technology, on both device andapplication levels, through the design and testing of a 50 kVA SiC BJT inverter as a building block for high-power HVDCinverters and design assessment of an ultra-high voltage 10 kV SiC BJT power device.According to TSB's Offshore Renewable Energy Catapult, the offshore renewable industry contributed circa £1bn to the UKeconomy and supported 20,000 jobs in 2013. However, only 40% of the lifetime costs of currently operational UK offshorewind farms will be spent domestically, since most large-scale components are imported. This project supports theexploitation of a new HVDC technology, currently only supplied by non-UK suppliers, such as Siemens and ABB.Successful commercialisation of project outcomes will not only reduce the LCOE from offshore renewables, but will alsoincrease the UK content of the supply chain, hence bring economic benefits and create new jobs across the supply chain.

该项目是Zagres Limited和剑桥大学工程系（CUED）之间的合作，旨在通过构建和测试一个原型50千伏安的SiC BJT逆变器，作为高压直流（HVDC）传输应用的构建块，研究、证明和量化新开发的碳化硅双极结晶体管（SiC BJT）技术的性能和经济性。SiC BJT功率模块技术的电压、频率和热额定值大大高于现有的基于si的模块，这可以显着减小尺寸，提高电力电子逆变器的可靠性和效率。这些好处将有助于降低海上可再生能源的能源成本。50kva SiC BJT逆变器将是同类产品中的第一个，并将作为开发和工业化大型超高压直流SiC逆变器的垫脚石。将评估逆变器的性能和优势，并与现有的基于硅的商业解决方案进行比较。此外，我们会制定一份详尽的商业计划和开发模式，以支持后续的商业化。该项目旨在通过设计和测试一个50千伏安的SiC BJT逆变器作为大功率高压变频器的构建模块，以及设计评估一个超高压10千伏的SiC BJT功率器件，来证明和量化SiC BJT技术在器件和应用层面的效益和经济性。根据TSB的海上可再生能源弹射器，2013年海上可再生能源产业为英国经济贡献了约10亿英镑，并提供了2万个就业岗位。然而，目前运营的英国海上风电场只有40%的生命周期成本将用于国内，因为大多数大型部件都是进口的。该项目支持开发一种新的高压直流技术，目前仅由西门子和abb等非英国供应商提供。项目成果的成功商业化不仅会降低海上可再生能源的LCOE，还会增加英国在供应链中的含量，从而带来经济效益，并在整个供应链中创造新的就业机会。
