Power converters play a key role in converting electric power to power all types of electrical loads in the world. Thermal management is essential to the reliability of power converters as excessive temperatures of the critical components such as transformers and semiconductors are the primary causes of failures in power converters. Nowadays the thermal management of power converters is becoming extremely challenging due to the increasing demand for high power density. Alpha Technologies Ltd. (ATL), the preeminent total power solutions provider, is planning to further increase the product reliability of their high-power-density rectifiers by replacing the active cooling with passive cooling. ATL desires a new and innovative thermal management strategy, which is mainly based on heat conduction and can maintain all components within their safe temperature limits Dr. Li's Electronics Cooling & Multiphase Flows Lab and Drs. Eberle and Wang's Power Electrics Lab at UBC Okanagan will collaborate with ATL to develop the conduction-based passive cooling for ATL's power modules. The project will be conducted both experimentally and numerically. The project will involve multiphysics modeling of magnetic components and detailed thermal analyses at the levels of power module and magnetic components. Innovative concepts of thermal management will be investigated and developed to address the thermal challenges for magnetic components. The developed technology will be tested and transferred to ATL. The proposed project will open up great potential of applying passive-cooling thermal design in high-power-density converters. This is highly important for power industry to meet the power requirements for a variety of system applications with the highest efficiency and reliability. The project fits into Canada's agenda to support industry competitiveness as the research will enhance Canada's competitiveness in the global industry of power electronics.

电源转换器在将电力转换为各种类型的电力负载方面发挥着关键作用。热管理对电源变换器的可靠性至关重要，因为变压器和半导体等关键部件的温度过高是电源变换器故障的主要原因。目前，由于对高功率密度的需求不断增加，电源转换器的热管理变得非常具有挑战性。卓越的整体电源解决方案提供商Alpha Technologies Ltd. （ATL）正计划通过用被动冷却取代主动冷却来进一步提高其高功率密度整流器的产品可靠性。ATL需要一种新的创新热管理策略，主要基于热传导，并能将所有组件保持在其安全温度范围内。Eberle和Wang在UBC Okanagan的电力电气实验室将与ATL合作，为ATL的电源模块开发基于传导的被动冷却技术。该项目将进行实验和数值计算。该项目将涉及磁性元件的多物理场建模以及功率模块和磁性元件层面的详细热分析。将研究和开发热管理的创新概念，以解决磁性元件的热挑战。开发的技术将进行测试并转让给ATL。该项目将为在高功率密度变流器中应用被动冷却热设计开辟巨大的潜力。这对于电力工业以最高的效率和可靠性满足各种系统应用的电力要求非常重要。该项目符合加拿大支持行业竞争力的议程，因为该研究将提高加拿大在全球电力电子行业的竞争力。
