本文介绍了最近的进展，在加速PEEC为基础的电磁仿真和复杂的母线结构的设计，用于多电平功率变换器的影响。所提出的方法包括不同的专用加速方法，用于不同的设计任务。应用的第一种加速技术是所谓的磁阻矩阵方法，用于全3D场结果，将存储器消耗减少了几个数量级，并将计算时间减少了3到5倍。所应用的第二种加速方法基于用于端口到端口阻抗提取的模型降阶技术，将计算时间减少约一个数量级，并允许宽带宏建模用于系统级仿真。本文重点介绍了这些方法的应用显示实际母线设计任务的影响。
This paper presents recent progress in the acceleration of PEEC based electromagnetic simulations and its impact on the design of complex bus bar structures as used in multilevel power converters. The approach presented consists of different dedicated acceleration methods for the different design tasks. The first acceleration technique applied is the so called reluctance matrix method for full 3D field results, reducing memory consumption by orders of magnitude and computing time by a factor 3 to 5. The second acceleration method applied is based on model order reduction techniques for port-to-port impedance extraction, reducing the computation time by about one order of magnitude and allowing wideband macro modeling for system level simulations. The paper focuses on the application of these methods showing the impact on practical bus bar design tasks.
