Abstract
A PSU including a primary side, including: a buck capacitor; and a PFC in electrical communication with the buck capacitor; a secondary side, including: a super capacitor; and a converter in electrical communication with an output of the primary side and in electrical communication with the super capacitor, wherein in a first state, the PFC receives energy from a source of energy, and in response: provides the energy to i) charge the buck capacitor based on a SOC of the buck capacitor, ii) charge the super capacitor based on a second SOC of the super capacitor; and iii) an IHS coupled to the PSU, wherein in a second state, the PFC ceases to receive energy from the source of energy and in response: the buck capacitor discharges to provide energy to the IHS; after the buck capacitor is completely discharged, the super capacitor discharges to provide energy to the IHS.
