Analysis of the dynamic characteristics of a power semiconductor module, considering the influence of electromagnetic coupling between wiring

The dynamic characteristics of power semiconductor modules were investigated. The switching behavior of power modules is strongly influenced by electromagnetic coupling. Therefore to design highly reliable power modules, it is important to establish a method of analyzing their dynamic characteristics which considers these electromagnetic phenomena. The parasitic parameters of wiring in a power semiconductor module were determined using three-dimensional electromagnetic field analysis and their dynamic characteristics were analyzed using these parameters. The analysis results showed good agreement with the experimental results
