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. The research program is expected to generate a number of leading-edge technologies and innovative designs for the high-power MV drives, which include novel SiC voltage source and current source converters, next generation 10kV-class transformerless drives, and advanced modulation and control algorithms for the MV drives. The developed technologies are expected to be utilized in the Canadian drive industry to enhance the performance of their products, reduce the manufacturing cost, and increase the productivity, making contributions to the Canada's economic growth.

兆瓦级大功率变流器广泛应用于钢铁、采矿、电力、可再生能源和石化等行业。随着技术的进步，一种新型的半导体开关器件--碳化硅开关应运而生。它们比目前在大功率变流系统中使用的其他开关器件更高效、更快速，其电压和电流处理能力开始达到可以实际应用于大功率变流器的水平。该研究计划的主要目标是开发基于碳化硅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。 该研究计划预计将为大功率中压驱动器产生多项尖端技术和创新设计，其中包括新型碳化硅电压型和电流型变流器、新一代10KV级无变压器驱动器，以及中压驱动器的先进调制和控制算法。预计所开发的技术将用于加拿大驱动行业，以提高其产品的性能，降低制造成本，提高生产率，为加拿大的经济增长做出贡献。
