Abstract
A method and circuit for a power supply unit (PSU) suitable for use in an information handling system to detect an inrush current reaching an inrush current threshold, to fully turning off, by a control circuit of the PSU, a series transistor to block the inrush current, to transfer, while the series transistor is fully turned off, magnetic energy stored in a boost choke to a bulk capacitor, and to fully turn on, by the control circuit of the PSU, the series transistor again immediately after the series transistor was in a fully turned off state, wherein the fully turning on occurs after the magnetic energy stored in the boost choke has been transferred to the bulk capacitor.
