Abstract

An adaptive power system includes an energy source, a bidirectional current source electrically connected between the energy source, and a power distribution bus of a power distribution system. The bidirectional current source delivers and absorbs power from the power distribution system to buffer a dynamic load profile of a dynamic load. The adaptive power system also includes a control loop and signal filter to control the bidirectional current source and regulate energy stored in the energy source.

Claims (29)

1. An adaptive power system comprising:

an energy source;

a bidirectional current source configured to be electrically connected between the energy source and a power distribution bus of a power distribution system, wherein the bidirectional current source is configured to deliver and absorb power from the power distribution system to buffer a dynamic load profile of a dynamic load;

an electromagnetic interference filter disposed between the power distribution system and the dynamic load; and

a control loop and signal filter configured to control the bidirectional current source and regulate energy stored in the energy source.

2. The adaptive power system of claim 1 , wherein the energy source comprises a storage capacitor, a battery, a super capacitor, or super conducting magnetic energy storage.

3. The adaptive power system of claim 1 , wherein the energy source comprises a plurality of capacitors configured in a capacitor bank.

4. The adaptive power system of claim 1 , wherein the control loop comprises an energy compensation loop configured to maintain a voltage across the energy source.

5. The adaptive power system of claim 4 , wherein the energy compensation loop comprises a bandwidth control circuit.

6. The adaptive power system of claim 4 , wherein the energy compensation loop comprises a voltage droop circuit.

7. The adaptive power system of claim 1 , wherein the signal filter is configured to regulate a current output to the power distribution bus to provide dynamic current to the dynamic load.

8. The adaptive power system 1 further comprising a low pass filter disposed between the power distribution system and the dynamic load.

9. The adaptive power system of claim 1 , further comprising a plurality of the bidirectional current source modules electrically connected in parallel.

10. The adaptive power system of claim 1 , wherein the dynamic load comprises an energy sensor or energy weapon.

11. A power distribution system comprising:

a dynamic load;

a generator configured to supply power to the dynamic load via a power distribution bus; and

an adaptive power system comprising:

an energy source;

a bidirectional current source configured to be electrically connected between the energy source and the power distribution bus, wherein the bidirectional current source is configured to deliver and absorb power from the power distribution system to buffer a dynamic load profile of the dynamic load;

an electromagnetic interference filter disposed between the generator and the dynamic load; and

a control loop and passive signal filter configured to control the bidirectional current source and regulate energy stored in the energy.

12. The power distribution system of claim 11 , wherein the energy source comprises a storage capacitor, a battery, a super capacitor, or super conducting magnetic energy storage.

13. The power distribution system of claim 11 , wherein the capacitor comprises a plurality of capacitors configured in a capacitor bank.

14. The power distribution system of claim 11 , wherein the control loop comprises an energy compensation loop configured to maintain a voltage across the energy source.

15. The power distribution system of claim 14 , wherein the energy compensation loop comprises a bandwidth control circuit.

16. The power distribution system of claim 14 , wherein the energy compensation loop comprises a voltage droop circuit.

17. The power distribution system of claim 11 , wherein the signal filter is configured to regulate a current output to the power distribution bus to provide dynamic current to the dynamic load.

18. The power distribution system 12 , wherein the adaptive power system further comprises a low pass filter disposed between the bidirectional current source and the dynamic load.
