摘要： A method may include causing a first test current to be delivered for a period of time from a phase of a voltage regulator to a load coupled to the voltage regulator, the phase configured to deliver electrical energy to the load. The method may also include measuring a first measured output current associated with the first test current. The method may further include causing a second test current to be delivered from the phase to the load for the period of time, the second test current differing from the first test current by a known offset. The method may additionally include measuring a second measured output current associated with the second test current. The method may also include calculating the respective gain and the respective offset of the phase based on the first measured output current, the second measured output current, the period of time, and the known offset.

摘要： An information handling system may include at least one information handling resource and a power supply unit having a bulk capacitor for storing charge. The power supply unit may be configured to convert an alternating current waveform received at an input of the power supply unit from an input source into a direct current voltage for delivering electrical energy to a power bus for providing electrical energy to the at least one information handling resource. Responsive to a loss of the input source, the power supply unit may charge the bulk capacitor from electrical energy present on the power bus and generated by at least one other power supply unit coupled to the power bus. Responsive to an indication of a failure of the at least one other power supply unit, the power supply unit may discharge the bulk capacitor to the power bus.
