Abstract
A method includes measuring an initial voltage a bulk capacitor at a power supply, controlling a power factor correction circuit to disable charging of the bulk capacitor for a predetermined period of time, and measuring a final voltage at the bulk capacitor at completion of the period of time. The method further includes measuring a first average power provided to a load receiving power from the voltage converter, the load external to the power supply, and determining a capacitance of the bulk capacitor based on the initial voltage, the final voltage, and the first average power.
