How to design the copper busbar of a DC power supply unit
Instead of drowning you in formulas, we'll walk through the design logic step by step—how to size the copper busbar, control temperature rise, layout joints and holes correctly, and ensure that what looks good in CAD can actually be manufactured reliably at scale. In this new edition the calculation of current-carrying capacity has been greatly simplified by the provision of exact formulae for some common busbar configurations and graphical methods for others. Other sections have been updated and modified to reflect current practice. Copper Development. Busbars simplify high-current distribution, reduce clutter, and can improve reliability if sized correctly. They may be used in a variety of configurations ranging from vertical risers, carrying current to each floor of a multi-storey building, to bars used entirely within a.
