多层叠层母排杂散电感频率特性分析
|
摘要
叠层母排作为大容量电力电子装置中的主要连接部件,能够有效减小装置换流回路中的杂散电感,抑制开关瞬态过程中功率器件上非理想的电压尖峰。采用多电平拓扑的电力电子装置因其复杂的拓扑结构需采用多层叠层母排。多层叠层母排换流回路中包含的导体层在高频激励下会产生涡流,中间导体层中存在的涡流场会影响换流回路中电磁场分布,进而影响多层叠层母排高频下的杂散电感。分析了多层叠层母排与双层叠层母排高频杂散电感之间的差异。结合电磁场分析结果,定量地表征了多层叠层母排不同激励频率下杂散电感变化规律。并通过有限元仿真,验证了分析结果的准确性。
Laminated busbar is used as the main connecting component in large-capacity power electronic devices, which can effectively reduce the stray inductance of the current commutation loop. However, multilayer busbars used in complex multilevel converters demonstrate distinctive features compared with the double layer counterparts. The middle conductor in current commutation loop will influence the stray inductance especially under high excitation frequency. In order to precisely express the characteristics of the multilayer laminated busbar, we performed modeling process and analysis. The effect of eddy current is taken into account in the proposed method, which guarantee the accuracy of calculation. Based on the electromagnetic field analysis, the frequency characteristics of stray inductance are investigated.Finally, the analysis result is proved by three-dimensional finite element analysis(FEA) simulations.
