Disruptive power device technologies based on compound semiconductors such as Silicon Carbide (SiC) have become increasingly attractive for various applications because of their ability to operate at substantially higher temperature, power density, voltage and switching frequency than those of silicon devices, leading to significant inverter cost and weight reductions and reliability and efficiency improvements.Camvertec have developed a compact low-cost SiC traction inverter technology incorporating an ultra-fast drive circuit combined with an ultra-efficient integrated inverter topology with a unique thermal management that eliminates the need for a second cooling loop i.e. it uses engine coolant for power electronics cooling. The technology has compact and lightweight design and has enabled the inverter cost to be competitive to mainstream silicon-based traction inverters.This project aims to prove the feasibility of the technology by design, build and testing of a credible-sized 50 kW inverter for EV powertrain applications.

基于复合半导体（例如碳化硅（SIC））的破坏性动力设备技术对各种应用变得越来越有吸引力，因为它们在高度更高的温度，功率密度，电压，电压和切换频率上的能力比硅设备的功能高，导致大量逆变器的成本降低和效率的稳定性。超快速驱动电路与超高效的集成逆变器拓扑结合使用独特的热管理，消除了对第二个冷却环的需求，即它使用发动机冷却液进行电源电子冷却。该技术具有紧凑且轻巧的设计，使逆变器成本能够与主流硅的牵引力逆变器具有竞争力。该项目旨在通过设计，建立和测试50 kW iNVerter的EV Powertrain应用程序来证明该技术的可行性。
