Increasing global warming and depleting fossil fuels have led to a growing interest in utilizing clean renewable energy. Canada has huge potential for renewable energy production. However, the integration of renewable energy into the power grid is challenging due to the cost, complexity and implementation of the necessary infrastructure, and the intermittent nature of renewable power production. Power electronics inverters are the enabling technology for the integration of renewable energy such as wind and solar energy into the power grid. However, a large portion of the renewable power is lost to heat in the power conversion stage due to inefficiencies of the power inverters. Therefore, research efforts are needed not only to increase renewable power production but to also decrease power losses with the new efficient power conversion systems, and to overcome the current technological barriers in power inverters such as high inverter sizes, high cost, low reliability, and low power density. The number of grid-connected non-linear loads such as electric vehicles when charging is continuously increasing. The intermittent nature of renewable power and the increasing number of non-linear loads severely affect the grid power quality. Therefore, research is required to develop advanced power inverters not only to integrate renewable power into the grid but to also mitigate grid power quality issues. The proposed research program will develop new ultra high-efficiency and high-reliability DC-AC inverter technologies with the latest Wide Band Gap (WBG) and Gallium Nitride (GaN) devices for renewable energy integration and grid power quality improvement. This research program will develop new non-isolated single-stage buck-boost DC-AC inverters to reduce the number of power processing stages, power losses, cost, and size; Develop new single-stage isolated DC-AC inverters to improve efficiency and power density; Improve the reliability of the proposed new inverters by eliminating shoot-through, and reduce the magnetic volume by integrating the magnetic components; and Develop digital control strategies for the proposed inverters to integrate renewable energy sources and mitigate the grid power quality issues. The proposed research program in the long terms will build and implement various prototypes of the new DC-AC inverters meeting the design and constraints of commercial products, and commercialize the developed inverter technologies to bring a broader societal impact. The findings and technological advancement from the proposed research will be shared with Canadian power electronics companies, power utilities, power engineers and researchers. The proposed research program will provide industry-driven training and collaboration opportunities for students in renewable energy integration and conversion. The students trained through this research program will become highly qualified engineers and technology leaders in the Canadian workforce.

增加全球变暖和耗尽的化石燃料，导致人们对利用清洁可再生能源的兴趣越来越大。加拿大具有可再生能源生产的巨大潜力。但是，由于必要的基础设施的成本，复杂性和实施以及可再生能源生产的间歇性质，因此将可再生能源集成到电网上是具有挑战性的。电力电子逆变器是将可再生能源（例如风能和太阳能）整合到电网中的能力技术。但是，由于电力逆变器的效率低下，在电力转换阶段，可再生能源的很大一部分在电力转换阶段损失了。因此，不仅需要进行研究工作来增加可再生能源的产生，还需要通过新的有效的电力转换系统来降低功率损失，并克服当前的电力逆变器中的技术障碍，例如高逆变器尺寸，高成本，低可靠性和低功率密度。电网连接的非线性载荷的数量（如电动车）的数量不断增加。可再生能力的间歇性质和越来越多的非线性负载严重影响了电网功率质量。因此，需要进行研究来开发先进的功率逆变器，不仅要将可再生能源整合到网格中，还可以减轻网格电源质量问题。拟议的研究计划将开发新的超高效率和高可靠性DC-AC逆变器技术，并具有最新的宽带隙（WBG）和硝酸盐（GAN）设备，以进行可再生能源整合和电网功率质量改进。该研究计划将开发新的非分类单阶段降压DC-AC逆变器，以减少电源处理阶段，功率损失，成本和大小的数量；开发新的单级隔离DC-AC逆变器，以提高效率和功率密度；通过消除射击量来提高拟议的新逆变器的可靠性，并通过整合磁性组件来减少磁性体积；并为拟议的逆变器制定数字控制策略，以整合可再生能源并减轻电网电源质量问题。拟议的研究计划长期以来将建立和实施新的DC-AC逆变器的各种原型，满足商业产品的设计和约束，并将发达的逆变器技术商业化，以带来更广泛的社会影响。拟议研究的发现和技术进步将与加拿大电力电子公司，电力公司，电力工程师和研究人员共享。拟议的研究计划将为可再生能源整合和转换的学生提供行业驱动的培训和协作机会。通过该研究计划培训的学生将成为加拿大劳动力中高素质的工程师和技术领导者。
