Abstract: A power supply unit that allows measurement of the capacitance without interrupting operation of the unit is disclosed. The unit includes a controller that causes a voltage change of a capacitor from a first threshold voltage between two periods of time. The time difference of when the voltage reaches a second threshold voltage is measured and the capacitance is determined from the time measurement, voltage change and power dissipation. The determination of capacitance may be performed while the power supply unit is actively supplying power.

Abstract: In some implementations, power provided to a computing system, such as a rack system, may be interrupted. This interruption is detected, and in response, power from a battery backup system is directed to the computing system to replace the interrupted power source, which in some implementations may be a main AC power grid source. A signal is received indicating that a backup power source, for example a backup generator system, is online and prepared to deliver power to the computing system. For an initial period of time, this backup power source is prevented from providing power to the computing system. For example, the backup generator system may be providing power to a power supply unit of the computing system, but the power is not allowed to flow to the computing system. After the initial period of time passes, the power provided to the computing system by the battery backup unit is reduced at a particular rate of change while the power from the backup generator system is allowed to flow to the computing system through the power supply unit.
