Abstract

In one embodiment, a power distribution system includes a DC power input for receiving DC power from a renewable energy source, an AC power input for receiving AC power, a multi-phase pulse power output for transmitting multi-phase pulse power, an AC power output for transmitting the AC power, and a controller for allocating power to the multi-phase pulse power output and the AC power output.

First claim

What is claimed is:

1. A power distribution system comprising:
a direct current (DC) power input for receiving DC power from a renewable energy source;
an alternating current (AC) power input for receiving AC power;
a multi-phase pulse power output for transmitting multi-phase pulse power;
an AC power output for transmitting the AC power; and
a controller for allocating power to the multi-phase pulse power output and the AC power output.

2. The power distribution system of claim 1 wherein the multi-phase pulse power and the AC power are delivered to power circuitry in a building for powering end devices and wherein data is delivered with the multi-phase pulse power to one or more of the end devices.

3. The power distribution system of claim 1 wherein the multi-phase pulse power is delivered to an outlet operable to deliver the multi-phase pulse power or PoE (Power over Ethernet).

4. The power distribution system of claim 1 further comprising an Ethernet power controller in communication with a DC bus receiving the DC power from the renewable energy source and from an AC to DC converter at the AC power input.

5. The power distribution system of claim 1 further comprising a controller operable to allocate output of the DC power to the multi-phase pulse power output based on a load requirement of end devices.

6. The power distribution system of claim 1 further comprising a controller operable to monitor power usage and turn off one or more low priority power circuits when power load exceeds available power.

7. The power distribution system of claim 6 wherein the controller is operable to turn off said one or more low priority power circuits when the power load exceeds power available from the renewable energy source.

8. The power distribution system of claim 1 wherein the DC power is integrated at a 380 VDC bus.

9. The power distribution system of claim 1 wherein the multi-phase pulse power comprises three-phase pulse power at a voltage greater than 56 volts DC.

10. The power distribution system of claim 1 wherein the renewable energy source comprises at least one of a solar panel, a wind turbine, and a rechargeable battery.

11. An apparatus comprising:
an alternating current (AC) circuit breaker;
a renewable energy circuit breaker;
a multi-phase pulse power circuit breaker; and
a switch coupled to the multi-phase pulse power circuit breaker and operable to provide circuit breaker control.

12. The apparatus of claim 11 further comprising a pulse power circuit breaker and an AC power breaker.

13. The apparatus of claim 11 further comprising a combined AC and multi-phase pulse power circuit breaker.

14. The apparatus of claim 11 wherein the switch comprises a PoE (Power over Ethernet) switch in communication with a power controller.

15. The apparatus of claim 14 wherein the PoE switch is operable to receive voltage and current information for multi-phase pulse power circuits and AC power circuits.

16. A method comprising:
receiving alternating current (AC) power;
receiving direct current (DC) power from a renewable energy source;
integrating the AC power and the DC power at a power distribution system;
monitoring available power and power load;
transmitting the AC power; and
transmitting multi-phase pulse power comprising a plurality of phases of pulse power, wherein the pulse power comprises a plurality of DC voltage pulses with the DC voltage pulses offset between phases to provide continuous power.

17. The method of claim 16 further comprising converting the received AC power to DC power for integration with the DC power from the renewable energy source.

18. The method of claim 16 wherein the DC voltage pulses are at 56 volts or greater voltage.

19. The method of claim 16 wherein the multi-phase pulse power comprises three or more phases of 380 VDC pulse power.

20. The method of claim 16 further comprising prioritizing delivery of the AC power or the multi-phase power to one or more power circuits.

21. The method of claim 16 further comprising performing fault detection between the DC voltage pulses of the multi-phase pulse power.

22. An apparatus comprising:
an input for receiving direct current (DC) power from a renewable energy source;
an output for transmitting multi-phase pulse power and PoE (Power over Ethernet); and
a controller for monitoring available power, identifying one or more low priority power circuits, and disabling said one or more low priority power circuits when a power load exceeds said available power.

23. The apparatus of claim 22 further comprising an input for receiving alternating current (AC) power and an output for transmitting the AC power, wherein said one or more low priority circuits are configured for receiving the multi-phase pulse power, the PoE, or the AC power.

24. The apparatus of claim 22 wherein the multi-phase pulse power comprises a plurality of phases of pulse power, the pulse power comprising a plurality of high voltage pulses with the high voltage pulses offset between phases to provide continuous power, and wherein a low voltage fault detection is performed between the high voltage pulses.
