Abstract
A powerplane for use in a backplane power distribution system. The backplane includes a conductive sheet for distributing power from a power source to a load. The powerplane further includes source locations and load locations for coupling the conductive sheet to a power source and a load. The conductive sheet is provided with impedance variations for balancing the resistance of the conductive sheet between the source locations and load locations. The impedance variations are spaced apart voids with the separation between the voids decreasing towards the source locations, thereby promoting even distribution of current to all the load locations.
