SYSTEM AND METHODS FOR DISTRIBUTED UNINTERRUPTABLE POWER SUPPLIES
First Claim
1. A distributed uninterruptible power supply (UPS) for mounting in a data center rack, the distributed power system comprising:
- an input constructed to receive alternating current (AC) input power;
an AC bus coupled to the input;
a DC bus constructed to couple to at least one DC load in the data center rack;
a battery bus coupled to at least one battery; and
at least one power module having a first input coupled to the AC bus, a second input coupled to the battery bus, and an output coupled to the DC bus, the at least one power module constructed to generate DC power based on received power from at least one of the AC bus and the battery bus.

Abstract
According to one aspect, a distributed uninterruptible power supply (UPS) for mounting in a data center rack is provided. The distributed power system includes an input constructed to receive alternating current (AC) input power, an AC bus coupled to the input, a DC bus constructed to couple to at least one DC load in the data center rack, a battery bus coupled to at least one battery, and at least one power module. The at least one power module has a first input coupled to the AC bus, a second input coupled to the battery bus, and an output coupled to the DC bus and is constructed to generate DC power based on received power from at least one of the AC bus and the battery bus.

16. A method of providing direct current (DC) power to one or more DC loads in a data center rack via a distributed uninterruptable power supply (UPS), the method comprising:
-
receiving alternating current (AC) power from an external power source; distributing the received AC power to at least one power module via an AC bus; converting the received AC power to DC power via the at least one power module coupled to the AC bus; distributing battery power from a battery to the at least one power module via a battery bus; and providing output DC power to the one or more DC load in the data center rack derived from at least one of the received AC power and the battery power via the at least one power module. - View Dependent Claims (17, 18, 19, 20)
