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.

基于诸如碳化硅（SiC）的化合物半导体的破坏性功率器件技术对于各种应用已经变得越来越有吸引力，因为它们能够在比硅器件高得多的温度、功率密度、电压和开关频率下操作，从而显著降低逆变器成本和重量，提高可靠性和效率。Camvertec开发了一种紧凑型低-这是一种高成本SiC牵引逆变器技术，结合了超快速驱动电路和超高效集成逆变器拓扑结构，具有独特的热管理功能，无需第二个冷却回路，即使用发动机冷却液冷却电力电子设备。该技术具有紧凑和轻量化的设计，使逆变器的成本与主流的硅基牵引逆变器具有竞争力。该项目旨在通过设计，建造和测试适用于电动汽车动力系统应用的50 kW逆变器来证明该技术的可行性。
