Abstract
Within a power supply, the draw of power between redundant power sources are passively balanced. Within a power plane of the printed circuit board a first current distribution plane section is placed. First connector pins are used to electrically connect the first current distribution plane to the first power source. Second connector pins are used to electrically connect the first current distribution plane to the second power source. Moats are placed within the power plane of the printed circuit board so that within the first current distribution plane section a first current path from the first connector pins to a first central power distribution area is substantially symmetrical to a second current path from the second connector pins to the first central power distribution area. Output power current passes through the first central power distribution area.
