Laminated busbars are essential for highly efficient, high power density applications, especially in the electric transportation sector, due to their unique electrical and mechanical characteristics. Stray parameters in laminated busbars pose a real challenge to designers in industries and researchers in the field since controlling these are crucial in busbar performance. Laminated busbar inductance has been studied extensively in the literature. However, very few works have focussed exclusively on the capacitance of the laminated busbar. In this paper, the impacts of busbar physical parameters on capacitance are studied in detail using Finite Element Modelling (FEM) software, ANSYS Q3D Extractor. The variation of capacitances on laminated busbars concerning several factors such as the busbar dimensions, terminals and apertures on the busbar structure, conductor and insulator materials are analysed.
