Abstract

Claims (32)

1 . An apparatus configured to provide direct current (DC) power, through a wiring connection and a DC-DC buck converter, to a radio of a cellular base station, the apparatus comprising:

a first DC power supply comprising a power supply output electrically coupled through the wiring connection to the DC-DC buck converter configured to provide, at a converter output of the DC-DC buck converter and to a DC power input of the radio of the cellular base station, a first DC voltage that is less than or equal to a maximum DC voltage rating of the radio;

wherein the first DC power supply is configured to provide a second DC voltage at the power supply output that is greater than the maximum DC voltage rating of the radio of the cellular base station.

2 . The apparatus of claim 1 , wherein the first DC power supply comprises a DC-DC boost converter configured to increase a third DC voltage received from a second DC power supply to the second DC voltage.

3 . The apparatus of claim 2 , further comprising the second DC power supply configured to provide DC power to the first DC power supply.

4 . The apparatus of claim 1 , further comprising:

the wiring connection electrically connected between the power supply output and the DC-DC buck converter;

the DC-DC buck converter; and

the radio, of the cellular base station, configured to receive the first DC voltage from the converter output of the DC-DC buck converter.

5 . The apparatus of claim 4 , wherein the DC-DC buck converter is configured to provide a constant DC voltage to the DC power input of the radio of the cellular base station.

6 . The apparatus of claim 4 , wherein the DC-DC buck converter is configured to provide a converter output voltage whose magnitude equals a magnitude of a converter input voltage less a fixed voltage.

7 . The apparatus of claim 6 , wherein the DC-DC buck converter further comprises a converter input;

wherein the first DC power supply is further configured to provide a converter DC voltage at the converter input whose magnitude equals a magnitude of the maximum DC voltage rating of the radio of the cellular base station less a predetermined margin voltage plus the fixed voltage.

8 . The apparatus of claim 4 , wherein the DC-DC buck converter and the radio are configured to be mounted on a tower.

9 . The apparatus of claim 2 , further comprising:

the second DC power supply configured to provide DC power to the first DC power supply;

the wiring connection electrically connected between the power supply output and the DC-DC buck converter;

the DC-DC buck converter; and

the radio, of the cellular base station, configured to receive the first DC voltage from the converter output of the DC-DC buck converter.

10 . The apparatus of claim 9 , wherein the DC-DC buck converter is further configured to provide a constant DC voltage to the DC power input of the radio of the cellular base station.

11 . The apparatus of claim 10 , wherein the DC-DC buck converter is further configured to provide a converter output voltage whose magnitude equals a magnitude of a converter input voltage less a fixed voltage.

12 . The apparatus of claim 11 , wherein the DC-DC buck converter further comprises a converter input;

wherein the first DC power supply is further configured to provide a DC voltage at the converter input whose magnitude that equals a magnitude of the maximum DC voltage rating of the radio of the cellular base station less a predetermined margin voltage plus the fixed voltage.

13 . The apparatus of claim 9 , wherein the DC-DC buck converter and the radio are configured to be mounted on a tower.

14 . A method for providing direct current (DC) electrical power, through electrical conductors and a DC-DC buck converter, to a radio of a cellular base station, the method comprising:

generating a first DC power signal; and

providing, at a power supply output, the first DC power signal having a first DC voltage that is greater than a recommended maximum DC voltage of the radio of the cellular base station, wherein the power supply output is configured to be electrically coupled through the electrical conductors to the DC-DC buck converter which is configured to provide, at a converter output of the DC-DC buck converter and to a DC power input of the radio of the cellular base station, a second DC voltage that is less than or equal to the recommended maximum DC voltage of the radio of the cellular base station.

15 . The method of claim 14 , wherein providing the first DC power signal having the first DC voltage comprises increasing a third DC voltage to the first DC voltage that is greater than the recommended maximum DC voltage of the radio.

16 . The method of claim 14 , further comprising providing the second DC voltage at the converter output of the DC-DC buck converter.

17 . The method of claim 16 , wherein providing the second DC voltage comprises providing the second DC voltage that is a constant DC voltage.

18 . The method of claim 16 , wherein providing the second DC voltage comprises providing the second DC voltage whose magnitude equals a magnitude of a converter input voltage, at a converter input of the DC-DC buck converter, less a fixed voltage.

19 . The method of claim 18 , wherein providing the second DC voltage comprises providing a magnitude of a DC voltage at the converter input that equals the recommended maximum DC voltage of the radio of the cellular base station less a predetermined margin voltage plus the fixed voltage.
