Uninterruptible power supplies with control capabilities
First Claim
1. A distributed low voltage power system, comprising:
- a primary power source that distributes line voltage power during a first mode of operation and fails to distribute the line voltage power during a second mode of operation;
a secondary power supply coupled to the primary power source, wherein the secondary power supply comprises a controller and an energy storage device, wherein the controller receives the line voltage power during the first mode of operation, stores the line voltage power as reserve power in the energy storage device during the first mode of operation, and distributes the reserve power during the second mode of operation;
a power distribution module (PDM) coupled to the primary power source and the secondary power supply, wherein the PDM comprises a first power transfer device and a first output channel, wherein the PDM receives the line voltage power from the primary power source during the first mode of operation, and wherein the first power transfer device generates a first low-voltage (LV) signal using the line voltage power during the first mode of operation; and
at least one first LV device coupled to the first output channel of the PDM, wherein the at least one LV device operates using the first LV signal generated by the PDM during the first mode of operation, and wherein the at least one first LV device operates using a reserve LV signal based on the reserve power during the second mode of operation,wherein the LV signal is up to 100 VAC or up to 60 VDC.

Abstract
A distributed low voltage power system can include a primary power source that distributes line voltage power during a first mode of operation and fails to distribute the line voltage power during a second mode of operation. The system can also include a secondary power supply coupled to the primary power source, where the secondary power supply includes a controller and an energy storage device. The system can further include a power distribution module (PDM) coupled to the primary power source and the secondary power supply, where the PDM includes a first power transfer device and a first output channel. The system can also include at least one first LV device coupled to the first output channel of the PDM, where the at least one first LV device operates using a reserve LV signal based on the reserve signal during the second mode of operation.

15. A secondary power source, comprising:
-
at least one input channel configured to receive input power from a power source; an energy storage device coupled to the at least one input channel, wherein the energy storage device stores the input power, wherein the energy storage device converts the input power to reserve power; at least one output channel that receives, during a first mode of operation, the reserve power from the energy storage device, wherein the at least one output channel is configured to deliver the reserve power to at least one component of a low voltage (LV) power distribution system; and a controller that controls the flow of the input power from the at least one input channel to the energy storage device and the flow of the reserve power from the energy storage device to the at least one output channel, wherein the controller is configured to autonomously control delivery of the reserve power to at least one LV device when the input power ceases being delivered to the at least one input channel, wherein the delivery of the reserve power is autonomous relative to control of the input power delivered to the at least one LV device during a second mode of operation that is independent of the first mode of operation. - View Dependent Claims (16, 17, 18, 19, 20)
