| description | Laminated busbars offer numerous advantages over traditional busbars, cables, and wiring harnesses due to their
lower stray inductance, higher capacitance, and compact size. These characteristics make them particularly
well-suited for use in electric vehicles, where space is a constraint and reliable power distribution is critical.
This study presents the optimization of a laminated busbar for use in an electric car traction inverter.
The laminated busbar structure is simulated in the electrostatic, magnetostatic, and thermal domains
to optimize its stray parameters and thermal attributes using finite element analysis software. The
work has a step-by-step process that includes optimizing insulation material, conductor overlap area,
bending of terminals and their combined effect, and reducing the laminated busbar current density and
thermal gradient. The results demonstrate that the optimization significantly increases the parasitic
capacitance by 14.8%, reduces the stray inductance by 2.73% and thermal gradient by 2.34%, with negligible
variation in the stray resistance. This research provides a comprehensive account of the optimization process
of laminated busbars for electric vehicle traction inverters. |
