Abstract
An information handling system includes a power supply unit (PSU) and a power assist unit (PAU). The PSU provides a power rail to power a load, and a constant current indication that indicates whether the power supply unit is operating in a constant current mode. The PAU is coupled to the power rail, and includes a power storage element, a converter coupled to the power storage element and to the power rail, and a controller. The controller receives an enable signal when the constant current indication indicates that the first power supply unit is operating in the constant current mode, and in response, the controller directs the converter to convert a voltage from the power storage element and to a current to the power rail to meet an additional demand of the load for power.
