Influence of the cross-section forms of a power bus bar on its electrical and mass-dimensional characteristics
DOI: 10.21293/1818-0442-2025-28-1-20-26
Abstract: The article investigates the influence of the cross-sectional forms of a power bus bar (PB) on its electrical and mass-dimensional parameters to determine the optimal geometry for minimizing electromagnetic interference. Asymmetric and symmetric cross-sectional configurations of PBs, as well as shielded transmission lines (TL), are analyzed. The effects of conductor dimensions and the relative permittivity of the insulator on the per-unit length inductance (L), capacitance (C), and characteristic impedance (Z0) of the PB were modeled. The reduction in L and increase in C were evaluated as functions of higher conductor width-to-thickness ratios, as well as the use of insulators with elevated permittivity and reduced thickness. The study demonstrates the superiority of a shielded transmission line configuration with a rectangular central conductor for power PB applications.
Keywords: power bus bar, numerical modeling, per-unit length parameters
