Abstract

A system for providing electrical power to a load is provided. The system includes at least two inverters and at least two resonant circuits. The inverters are operative to electrically connect to a power source. The resonant circuits are each electrically connected to at least one of the inverters and operative to provide electrical power to the load. The resonant circuits are coupled to each other.

First claim

What is claimed is:

1. A system for providing electrical power to a load comprising:
at least two inverters operative to electrically connect to a power source;
at least two resonant circuits that are each electrically connected to at least one of the inverters and operative to provide electrical power to the load;
wherein the at least two resonant circuits are coupled to each other via a first inductance by a first inductor and a second inductance by a second inductor; and
wherein the at least two resonant circuits are coupled to each other via the first and the second inductors disposed within the resonant circuits.

2. The system of claim 1 , wherein each inverter is operative to connect to the power source via one or more input leads, and the at least two resonant circuits are further coupled to each other via one or more additional inductors disposed in the input leads.

3. The system of claim 1 , wherein the at least two inverters and the at least two resonant circuits are connected in series to the load.

4. The system of claim 1 , wherein the at least two inverters and the at least two resonant circuits are connected in parallel to the load.

5. The system of claim 1 , wherein each inverter is electrically connected to two of the at least two resonant circuits.

6. The system of claim 1 , wherein the at least two inverters are operative to vary the electrical power provided to the load.

7. The system of claim 1 further comprising an electromagnetic radiation based imaging device having a radiation source; and wherein the radiation source is the load.

8. A method of providing electrical power to a load comprising:
providing electrical power to the load via one or more resonant circuits that are each electrically connected to at least one of two inverters that are electrically connected to a power source;
wherein the resonant circuits are coupled to each other via a first inductance by a first inductor and a second inductance by a second inductor;
wherein the resonant circuits are coupled to each other via the first and the second inductors disposed within the resonant circuits.

9. The method of claim 8 , wherein each inverter is electrically connected to the power source via one or more input leads, and the resonant circuits are further coupled to each other via one or more additional inductors disposed in the input leads.

10. The method of claim 8 , wherein the two inverters and the one or more resonant circuits are connected in series to the load.

11. The method of claim 8 , wherein the two inverters and the one or more resonant circuits are connected in parallel to the load.

12. The method of claim 8 , wherein each inverter is electrically connected to two of the one or more resonant circuits.

13. The method of claim 8 further comprising varying the power provided to the load via at least one of the two inverters.

14. A non-transitory computer readable medium storing instructions configured to adapt a controller to:
vary electrical power provided to a load by a first resonant circuit and a second resonant circuit that are both connected to at least one of two inverters that are electrically connected to a power source, wherein the first and the second resonant circuits are coupled to each other via a first inductance by a first inductor and a second inductance by a second inductor disposed in the first and the second resonant circuits, respectively;
wherein the controller adjusts at least ne of the two inverters by controller one or more switches disposed within the inverters.

15. The non-transitory computer readable medium of claim 14 , wherein the stored instructions adapt the controller to vary the electrical power by adjusting at least one of the two inverters.

16. The non-transitory computer readable medium of claim 15 , wherein the inverters are fully-bridged.

17. The non-transitory computer readable medium of claim 14 , wherein the load is a radiation source of an electromagnetic radiation based imaging device.
