High-power converters in the megawatt range are widely used in industry, such as steel, mining, power utility, renewable energy and petrochemical industries. With the technological advancement, a new type of semiconductor switching devices, the silicon carbide (SiC) switches, have emerged. They are more efficient and fast than the other switching devices currently used in the high-power conversion systems, and their voltage and current handling capability starts to reach a level that can be practically used in high-power converters. The main objective of the proposed research program is to develop SiC device based high-power converters and their control schemes for next generation medium voltage (MV, 2.3kV – 13.8kV) motor drives for higher energy efficiency and better system performance.

兆瓦级范围内的大功率转换器广泛应用于工业中，例如钢铁、采矿、电力公用事业、可再生能源和石化工业。随着技术的进步，出现了一种新型的半导体开关器件-碳化硅（SiC）开关。它们比目前在大功率转换系统中使用的其他开关器件更高效、更快，并且它们的电压和电流处理能力开始达到可以实际用于大功率转换器的水平。该研究计划的主要目标是开发基于SiC器件的大功率变流器及其控制方案，用于下一代中压（MV，2.3kV - 13.8kV）电机驱动，以实现更高的能效和更好的系统性能。
