Balancing power distribution in a power supply system with redundant power sources
First Claim
1. A method for providing a substantially balanced draw of power between a first power source and a second power source, each connected to a printed circuit board, the method comprising the following steps:
- (a) placing a first current distribution plane section within a power plane of the printed circuit board;
(b) electrically connecting first connector pins to the first current distribution plane and to the first power source;
(c) electrically connecting second connector pins to the second current distribution plane and to the second power source;
(d) placing moats 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; and
,(e) providing output power utilizing current which passes through the first central power distribution area.

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.

8. A power supply for providing power to a computing system, comprising:
-
a first power source connector for receiving a first power signal from a first power source; a second power source connector for receiving a second power signal from a second power source; a printed circuit board on which is placed the first power source connector and the second power source connector, the printed circuit board including a power plane, the power plane including a first current distribution plane section, and moats placed within the power plane of the printed circuit board, the moats being placed so that within the first current distribution plane section, a first current path from first connector pins of the first connector to a first central power distribution area is substantially symmetrical to a second current path from second connector pins of the second connector to the first central power distribution area. - View Dependent Claims (9, 10, 11, 12, 13, 14)
