Power Electronics for Adverse High Temperature Environments (PEATE)

该S2B基础研究项目的重点是开发一系列基于SiC技术的电力电子器件，用于高温高压恶劣环境。在天然气生产行业中，用于井下作业的压缩机需要在井下环境中工作，通常在100至200℃的范围内，压力高达90 bar。压缩机的额定功率高达500kw，压缩机通过2.4 kV直流母线的电力电子驱动器供电，使用额定3.3 kV和50a的设备。传统的硅基电力电子设备的最大工作结温限制在150℃以下，井下环境的最大上限约为105℃。低电流和高温度有助于当前和近期SiC的能力,从而形成一个理想的概念验证演示项目的总体目标是调查技术的发展将使电力电子转换器在气体及其它可以操作环境温度150 c,这一目标将通过协同意识到项目的工作地址半导体技术、包装技术、传热、变频器控制和可靠性在七个技术工作包。虽然该项目的目标是在井下气体压缩机（DGC）中用于气井加压，但该项目的成果将在所有极端温度环境中得到应用，其中SiC技术可以在未来发挥作用，包括航空航天，军事，能源，汽车，输电和配电。

This S2B Basic Research Project is focussed on the development of a family of power electronic devices based on SiC technology for application in hostile environments of high temperature and pressure. Compressors for down-well operation in the gas production industry are required to work in the well ambient, which is typically in the range 100 to 200 C at pressures of up to 90 bar. Ratings for the compressor are up to 500 kW, the compressor being supplied through a power electronic drive from a 2.4 kV dc-buss using devices rated at 3.3 kV and 50 A.Conventional Si-based power electronics is limited to maximum operating junction temperatures of less than 150 C, giving a maximum down-hole ambient ceiling of around 105 C. This combination of relatively high voltage, low current and high temperature lends itself to the current and near future capability of SiC and it thus forms an ideal proof-of-concept demonstrator The overall aim of the project is to investigate technologies that will enable the development of a power electronic converter for a DGC that can operate in a gas ambient temperatures of up to 150 C. This aim will be realised through a co-ordinated programme of work that addresses semiconductor technology, packaging technology, heat transfer, converter control and reliability in seven technical work packages. Although the programme is directed at a potential application in a down-well gas compressor (DGC) for pressure boosting in gas wells, the results of this project will find application in all extreme temperature environments in which SiC technology could play a future role including aerospace, military, energy, automotive, transmission and distribution.
