随着宽带隙(WBG)功率器件封装领域出现新的挑战和技术，电力电子模块的设计受到了新的关注。为了满足这些高速晶体管的需求，需要新的技术来生产在不超过器件或其封装材料的工作温度的情况下减少寄生和噪声产生的模块。传统上，电源模块设计一直是一个高度迭代的过程-使用有限元分析(FEA)工具反复修改和模拟设计，这需要大量的人力和计算时间。为了克服这些问题，名为PowerSynth的电子设计自动化工具(EDA)正在朝着基于电气和热标准的电源模块布局综合和优化方向发展。本文介绍了如何扩展PowerSynth的功能以减少电磁干扰(EMI)来优化布局。介绍了基于噪声传播路径传递函数的优化策略，并将结果与有限元仿真结果进行了比较。
The design of power electronics modules is undergoing renewed interest as new challenges and technologies emerge in the realm of wide bandgap (WBG) power device packaging. In order to meet the demands of these high-speed transistors, novel techniques are required to produce modules with reduced parasitics and noise generation without exceeding the operating temperature of the devices or their packaging materials. Traditionally, power module design has been a highly iterative process—repeatedly reworking and simulating designs using finite element analysis (FEA) tools that require considerable time in terms of both labor and computation. To overcome these issues, an electronic design automation tool (EDA) known as PowerSynth is ongoing in its development toward power module layout synthesis and optimization based on electrical and thermal criteria. In this paper, work to extend the capabilities of PowerSynth to optimize layouts with reduced electromagnetic interference (EMI) is presented. Optimization strategies based on the transfer functions of noise propagation paths are introduced and results showing layouts with reduced noise generation are compared with FEA simulations.
