Abstract
A power supply system for an information handling system is disclosed. The power supply system includes power supply units electrically coupled via an output line. The power supply units are configured to supply an output voltage to the output line. Each power supply unit receives a feedback signal indicative of a voltage of the output line and a programmed voltage signal indicative of a supply voltage required for the output line. A standby power supply unit is configured to transition between a standby mode and an active mode based, at least in part, on the feedback signal and the programmed voltage signal. Power supply units are configured to transition to a load sharing mode where the power supply units cooperatively supply an output voltage to the output line. The transitioning is based, at least in part, on the feedback signal and the programmed voltage signal.
