Abstract
A system and method is directed to charging and discharging an energy-tank capacitor of a power supply unit (PSU) in a computing system. The PSU has a forward converter, a buck converter, a switch box, and an option box. The forward converter has a transformer. A primary winding of the transformer is coupled to an input of the PSU, while a secondary winding of the transformer is coupled to an output of the PSU. Two or more components of the forward converter are shared with the buck converter to support the functionality of the buck converter when it is enabled. The switch box has a power switch and a controller switch connected to the forward converter. The energy stored on the energy-tank capacitor is capable of supporting power consumption of the server system during a hold-up time, when an input power to the PSU is interrupted.
