中文摘要

本文提出了一种针对功率变换器叠层母排的拓扑优化方法,旨在满足温度限制的前提下最小化铜材使用量。叠层母排因其对换流回路杂散电感的贡献而备受关注,但散热性能研究对于控制热点、提升功率密度及可靠性同样至关重要。

English Abstract

This paper focuses on a topology optimization method for laminated busbars in power converters that minimizes the quantity of copper used while keeping the temperature under the allowed limits. Busbars are widely studied for adding their stray inductance to the commutation loop, which causes surge voltage across the power devices. However, the study of heat dissipation is essential to control hots...
