High-voltage busbar DC resistance

For a rectangular copper busbar, DC resistance per metre is R = rho / (width x thickness) in micro-ohms/m. AC resistance includes the skin effect factor: Rac = Rdc x ks. Plan for continuous current + surge; hotspots often occur at studs and terminations, not in the bar body. Keep symmetry in multi-branch systems to avoid uneven current sharing. Although the percentage of loss is obviously far greater with a 1-V rail versus a 15-V rail for a given voltage drop, the voltage drop itself is unaffected. Some applications in terms of rated power and shape are investigated regarding their particular requirements and challenges. Silicon Carbide (SiC) power devices switch at much. Voltage drop is wel...
