发明名称 Soft power-up for an external power adapter
摘要 An external power adapter prevents damage to contacts of power connectors by reducing current in-rush when the powered-up external power adapter is coupled to an information handling system. A control signal from the information handling system is used to initiate a voltage output of the external power adapter such that substantially no voltage is present on the contacts of the power connectors until the control signal is detected by the external power adapter. The external power adapter may determine the presence of an electrical load before applying the output voltage to the information handling system. The output voltage may be ramped from substantially no voltage to operating voltage over a period of time.
