Most industrial processes use power electronics to draw power from the electrical utility power grid. For instance, industrial electric motor-drive systems are a prominent means for many industrial processes to reduce energy consumption, hence lowering operating costs and contributing to efforts for more environmental friendly electric power systems. In addition, most of the prominent alternative and sustainable energy systems rely on power electronic technology to control and store electric power. The main technical goals of this program are to provide innovations in the design of power electronics used in two main application areas: electric vehicles and industrial electric motor-drives. The size, weight, cost and operational lifetime of electrical power conversion systems are affected by their power conversion efficiency. For instance, a more efficient electrical motor-drive system for electric vehicles can lower the weight and size of the motor and its cooling system: cheaper components and longer operational lifetimes can then result. Thus, a central theme of this research is the creation of new higher efficiency electric power conversion technology. More specific technical goals are to improve the design of the power electronics and their control, for example, innovations are expected in: (a) the systems used to store electrical energy in battery arrays such as used in electric vehicles; (b) motor-drive power electronic topology designs that better exploit the benefits that capacitors and coupled inductors can provide: capacitors are lightweight with a high energy storage density, coupled inductors have a high reliability and long lifetimes. This program will result in commercially feasible technology grounded in their practical application. Academic researchers and HQP will gain knowledge and experience in the design and the operation of industrial drive systems and electric vehicles. Canadian companies will benefit from the HQP and technical innovations generated. The program will contribute to the need of Canadians for a more environmental friendly industrial sector using cost effective energy efficient sustainable energy systems.

大多数工业过程使用电力电子设备从电力公用电网汲取电力。例如，工业电动机驱动系统是许多工业过程减少能耗的重要手段，因此降低了运行成本并有助于更环保的电力系统。此外，大多数著名的替代和可持续能源系统都依赖于电力电子技术来控制和存储电力。 该计划的主要技术目标是为两个主要应用领域的电力电子设计提供创新：电动汽车和工业电动机驱动器。电力转换系统的尺寸、重量、成本和操作寿命受到其电力转换效率的影响。例如，一个更高效的电动汽车电机驱动系统可以降低电机及其冷却系统的重量和尺寸：更便宜的组件和更长的使用寿命。因此，本研究的中心主题是创造新的更高效率的电力转换技术。更具体的技术目标是改进电力电子器件及其控制的设计，例如，预期在以下方面进行创新：（a）用于在电池阵列中存储电能的系统，例如在电动车辆中使用的电池阵列;（B）更好地利用电容器和耦合电感器可以提供的益处的电机驱动电力电子拓扑设计：电容器重量轻，具有高能量存储密度，耦合电感器具有高可靠性和长寿命。 该计划将导致商业上可行的技术，并以其实际应用为基础。学术研究人员和HQP将获得工业驱动系统和电动汽车的设计和操作方面的知识和经验。加拿大公司将从HQP和技术创新中受益。该计划将有助于加拿大人的需要，一个更环保的工业部门使用成本效益高的能源效率的可持续能源系统。
