A computer power system comprises an AC-to-DC power supply for providing DC power to the computer during the presence of AC line power and a backup power supply for providing DC power from batteries directly to the DC operated components of the computer system, completely bypassing the AC to DC power supply, when AC line voltage is absent or low.

Unique computer power system with backup power

A. Power supply comprising an AC to DC power supply and a DC to DC power supply and a DC battery charging circuit within a single device, which device provides continuous DC power to a load regardless of the presence or absence of the AC power source.

Power-supply/battery back-up power supply/battery charger combination

Power supply comprising an AC to DC power supply and a DC to DC power supply and a DC battery charging circuit within a single device, which device provides continuous DC power to a load regardless of the presence or absence of the AC power source.
