Direct Current Power Distribution and Fault Protection
First Claim
1. A power distribution system, comprising:
- a high-voltage direct current unit (HVDCU) configured to receive high-frequency alternating current (AC) input power from a power source and including a power factor correction (PFC) unit and a DC-DC high-voltage converter;
wherein the PFC unit is configured to convert the high-frequency alternating current input power into an intermediate DC power and the DC-DC high voltage converter is configured to process the intermediate DC power into distribution DC power, wherein the distribution DC power is of a lower voltage than the intermediate DC power;
a negative voltage distribution rail configured to provide −
28 VDC of the distribution DC power and a positive voltage distribution rail configured to provide +28 VDC of the distribution power to at least one control unit (CU);
each the CU being configured to convert the distribution DC power into output power compatible with at least one load and supply the output power to the loads associated with it; and
wherein the loads include at least one selected from the group consisting of electronic display, AC consumer power outlet, USB power outlet, passenger address system, wireless access point and personal electronic device.
