Secondary power for critical loads for railroad

摘要

In a locomotive having at least one electrical load connected to at least one power source via a locomotive power carrying bus, a system for ensuring a current connection between the at least one power source and the at least one electrical load is provided. The system includes a first rectification device, wherein the first rectification device is connected between the at least one electrical load and the locomotive power carrying bus to provide a rectified current connection between a first power source and the at least one electrical load. The system further includes a second rectification device, wherein the second rectification device is connected between the at least one electrical load and the locomotive power carrying bus to provide a current connection between a second power source and the at least one electrical load and at least one auxiliary rectification device, wherein the at least one auxiliary rectification device is connected to the at least one electrical load and at least one of the first rectification device and the second rectification device to ensure a continuous current connection between the at least one power source and the at least one electrical load.
