To meet the growing demand for electrical energy while reducing environmental impact, electrical systems of the future will need to be much more energy efficient. High-power electric motor drives are the major consumers of electrical energy and they have significant potential for improvement in terms of energy saving. The key to this improvement is advances in power electronics technology. The proposed research will focus on advancing the state-of-the-art in power electronic technologies that operate in the medium-voltage (MV) range (2.3 to 15kV) for motor drive applications. High-power MV drives have a wide range of applications in the oil and gas, chemicals, mining and metals, cement, power generation and utilities, traction, and food and beverage industries. Energy efficiency, power quality, cost, size, reliability, fault protection, and easy installation and maintenance are the main challenges in the development of power electronics for high-power MV motor drives. Although existing MV power electronic converters based on the concept of multilevel structure have advantages over the conventional converters, their voltage level is still limited to 6.9kV. This is because of the limitation in voltage rating of the available power semiconductors in the market and the structure of the current multilevel MV power converters. The existing solutions for higher voltage need to employ a complex transformer, which is not efficient, or use a modular topology with a significant increase in the number of components which is not cost-effective and reliable. The proposed research program will focus on a novel family of modular and scalable power conversion structure for further expansion of MV drives for higher voltage (>6.9kV) applications with improved efficiency, performance, cost, size, weight, reliability, and fault detection capability. It is expected that the theoretical results and the successful implementation of this proposed research program will provide a new set of power electronic topologies and advanced control techniques to introduce new technologies in the area of high-power MV drives which will produce significant energy savings for all sectors using industrial electric motors. This research program will also help to educate the next generation of power engineers with required knowledge and technical skills to contribute to local and national businesses and industries.

为了满足对电能的不断增长的需求，同时减少环境影响，未来的电气系统将需要更加节能。高功率电动机驱动器是电能的主要消费者，它们在节能方面具有巨大的改善潜力。这种改进的关键是电力电子技术的进步。拟议的研究将着重于推进在中型电压（MV）范围内（2.3至15kV）的电力电子技术的最新技术，用于运动驱动应用。 高功率MV驱动器在油气，化学，采矿和金属，水泥，发电和公用事业，牵引力以及食品和饮料行业中具有广泛的应用。能源效率，功率质量，成本，尺寸，可靠性，故障保护以及易于安装和维护是开发高功率MV电动机驱动器电力电子设备的主要挑战。尽管基于多级结构概念的现有MV功率电子转换器比常规转换器具有优势，但它们的电压水平仍限制为6.9kV。这是因为市场上可用的功率半导体的电压额定值以及当前多级MV功率转换器的结构的限制。现有的更高电压的解决方案需要采用不高效的复杂变压器，或使用模块化拓扑，而成分的数量显着增加，这并不具有成本效益且可靠。 拟议的研究计划将重点关注一个新型的模块化和可扩展功率转换结构的家族，以进一步扩展MV驱动器，以提高效率，性能，成本，大小，重量，可靠性和故障检测能力，以提高效率，性能，成本，尺寸，重量，可靠性和故障检测能力。预计该提出的研究计划的理论结果和成功实施将提供一套新的电力电子拓扑和高级控制技术，以在高功率MV驱动器领域引入新技术，从而为所有工业电动机提供大量节能，从而为所有部门节省大量能源。该研究计划还将有助于教育下一代的电力工程师，并具有所需的知识和技术技能，以对本地和国家业务和行业做出贡献。
