Estimating a lifespan of a power supply

Abstract:

Estimating a lifespan of a power supply. An internal computerized component periodically obtains a set of measurements read from one or more sensors affixed to a power supply. Such measurements may measure ambient temperature, temperature of an electrolytic capacitor of a power supply, voltage across a power supply, and/or current from the power supply. The internal computerized component analyzes the set of measurements using, at least in part, a weighted set of factors, to obtain an estimate of a lifespan of a power supply. The estimated lifespan may be sent over an optical link or wireless network to an entity monitoring the lifespan of the power supply.
