Abstract:
1. An apparatus for providing an uninterruptible power source to a dual power device capable of being alternately powered through a primary power input connected to a primary power source or a secondary power input connected to a secondary power source, the apparatus comprising: a power input for receiving alternating current (AC) from the primary power source; an AC power output connected to the power input for delivering AC to the primary power input of the dual power device; one or more converter elements operative to receive the AC from the power input, to convert the AC to direct current (DC), and to deliver the DC to a power storage element; the power storage element connected to the one or more converter elements, the power storage element operative to store at least a portion of the direct current delivered from the converter elements, and wherein the stored power is delivered from the power storage element directly to a DC power output when the primary power source is disconnected; and the DC power output connected directly to the power storage element for delivering DC to the secondary power input of the dual power device.
