“…DC busbar made of laminated conductor plates, e.g. steel, aluminum, and copper, normally perform with high current conducting capabilities, low self-inductance due to mutual inductance cancellation, and high capacitive coupling energy and thus the state-of-the-art research has been to minimize the power loop inductance [243]- [246]. In [247], three different lamination schemes for the laminated MV DC busbars are evaluated in terms of radiated flux density and induced voltage overshoot, demonstrating a minor change in EMF magnitude between the three designs.…”

“…Laminated busbars provide compact connections with ample mechanical support while keeping the overall system footprint comparatively low. High power applications such as electric vehicles, motor drives and photovoltaic inverters commonly use laminated busbars [7][8][9]. Laminated busbars are essential in electric vehicle design since the size and weight of components are crucial constraints in electric transportation [10].…”

This paper presents a systematic investigation of the impact of physical parameters such as dimensions, apertures and terminals, on the busbar inductance. A planar laminated busbar with copper conductors and a polyamide insulator is studied using a 3D FEM (Finite Element Modelling) based simulation software. The impact of dimensions such as conductor length, width and thickness, depth of insulator, the effects of aperture number, size, position and connection terminals on the busbar inductance are examined. The magnetic flux density, current density involved and its dependence on the self and mutual inductance of the laminated busbar is analyzed. Laminated busbars provided lower inductance with decreased conductor length, thickness, aperture diameter and depth of insulator. Also, the increased width of the busbar is of the essence for the design of a low inductance busbar. Low inductance laminated busbars are highly beneficial in power converters, powertrain inverters in electric vehicles, photovoltaic converters.

“…They provide high power density while using much lesser space. Laminated busbars have more surface area to dissipate heat and are hence much more thermally viable than cables [4]. Laminated busbars also provide reduced stray inductance and increased capacitance for reducing the overall losses in the system.…”

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.
