Abstract
A system and a method are provided that allow load sharing between two or more DC output power supplies that are connected in parallel to scale the output power. As the temperature of the critical components in a power supply rises, the output voltage from that power supply will be lowered, so that the coolest supply will have the highest voltage and thus the highest current to the load. The systems and methods can operate without any additional wires connecting the supplies other than those supplying the power to the load.
