Abstract
A technique for preventing power interruptions and extending backup power life is provided. The technique automatically prevents power interruptions in a line between a power source and a load. The technique can also extend the operating life of the power source. In one embodiment, a circuit for preventing power interruptions is provided. The circuit may include at least one arrays of capacitors, with the capacitors being arranged in parallel within an array, at least one switching elements configured to couple the at least one array of capacitors to a load, and a controller operatively coupled to the at least one switching element. The controller is configured to selectively drive the at least one switching element based on predetermined criteria.
