Innovative conduction cooling for high-power-density converters

功率转换器在将电力转换为世界上所有类型的电力负载中起着关键作用。热管理对于电源转换器的可靠性至关重要，因为变压器和半导体等关键组件的温度过高是电源转换器故障的主要原因。如今，由于对高功率密度的需求不断增加，功率转换器的热管理变得极具挑战性。** Alpha Technologies Ltd.（ATL）是一家卓越的整体电源解决方案提供商，计划通过用被动冷却取代主动冷却，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，该策略主要基于热传导，可以将所有组件保持在其安全温度范围内 ** 李博士的电子冷却和多相流实验室以及Eberle博士和Wang博士在UBC Okanagan的电力电子实验室将与ATL合作，为ATL的功率模块开发基于传导的被动冷却。该项目将进行实验和数字。该项目将涉及磁性组件的多物理场建模以及功率模块和磁性组件级别的详细热分析。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。将对开发的技术进行测试并转让给ATL。 该项目将为被动冷却热设计在高功率密度转换器中的应用开辟巨大的潜力。这对于电力行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。

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.**
