Abstract

An electric power distribution system configured to facilitate transferring energy between an energy source and load. The distribution system may be configured or otherwise adapted to invert DC energy to AC energy when driving the load and to invert AC energy to DC energy when regenerating the energy source.

Claims

1. An electrical distribution system for inverting energy transferred between a vehicle battery and a vehicle load, the system comprising:

a DC/AC inverter in electrical communication with the battery, the inverter configured for inverter DC energy to AC energy; and

a AC/AC converter in electrical communication with the inverter and vehicle load, the converter configured to converter the AC energy output from the inverter for output to the vehicle load.

2. The system of claim 1 wherein the inverter is directly connected to the converter.

3. The system of claim 1 wherein the inverter is a full bridge inverter.

4. The system of claim 3 wherein the full bridge inverter includes four switches.

5. The system of claim 1 wherein the converter is a full bridge converter.

6. The system of claim 5 wherein the full bridge converter includes two switches to facilitate uni-directional operation.

7. The system of claim 5 wherein the full bridge converter includes four switches to facilitate bi-directional operation.

8. The system of claim 1 wherein the converter is a full bridge converter and the inverter is a full bridge inverter.

9. The system of claim 1 wherein the vehicle load is an electric motor configured to drive the vehicle as a function of the AC energy output of the converter.

10. The system of claim 9 wherein the motor, converter, and inverter are bi-direction so as to facilitate charging the battery with energy from the motor.

11. The system of claim 1 wherein the load is connected to the converter by way of a plug included on the vehicle, the load being separate from the vehicle.

12. The system of claim 1 wherein the converter and inverter are bi-direction so as to facilitate charging the battery with energy from a domestic wall outlet connect to a vehicle plug.

13. The system of claim 1 further comprising an input filter for filtering the DC energy and an output filter for filtering the AC energy outputted from the converter.

14. The system of claim 1 further comprising a common mode output filter connected between the converter and the vehicle load.
