Compact Semiconductor Modules Enabling Lighter & More Efficient Trains

在该项目中，我们将开发3.3kV/1.8kA反向导电IGBT （RC-IGBT）器件，以取代目前在轨道交通，风力发电和高压直流（HVDC）传输模块中使用的单独的IGBT和二极管芯片。与最先进的基于igbt的模块相比，RC-IGBT模块将提供更高的输出电流，更低的热阻，同时确保两倍长的电源循环寿命。我们将开发和优化RC-IGBT设备，主要用于列车的电力驱动，这将确保列车运行可靠、更节能、更环保，促进铁路网的发展，提高人员和货物的运输效率，这是城市化的关键推动因素。开发的3.3kV rc - igbt模块也可用于风力涡轮机和高压直流输电网络，并进一步扩展到1.2kV和1.7kV电压，用于电动汽车和太阳能光伏系统。因此，研发的RC-IGBT技术将以节能、可持续的方式为解决中国农村和城市人口面临的能源和交通挑战做出重大贡献。

Within this project we will develop a 3.3kV/1.8kA Reverse Conducting IGBT (RC-IGBT) devices to replace separate IGBT and Diode chips currently used in modules for rail transportation, wind power generation and High Voltage Direct Current (HVDC) transmission. Compared with the state-of-the-art IGBT-based modules, the RC-IGBT module will deliver higher output current, lower thermal resistance while ensuring twice as long powercycling lifetime. We will develop and optimise RC-IGBT devices primarily for electric drives for trains which will ensure reliable, more energy efficient and environmentally friendly operation of trains and facilitate growth of the rail network and more efficient transportation of people and goods, a key enabler for urbanisation. Modules with developed 3.3kV RC-IGBTs can also be used in wind turbines and HVDC transmission network and further extended to 1.2kV and 1.7kV voltages and used for electric vehicles and solar PV systems. Thus, the developed RC-IGBT technology will make a significant contribution in solving energy and transportationchallenges facing both rural and urban populations in China in an energy-efficient, sustainable manner.
