(EP867064-A2)      The uninterrupted power source forms part of a transfer system which ensures a supply of electrical power to on-board equipment during normal switching from one power supply to another, such switching being initiated either manually by the pilot, or automatically by the system. The transfer system has separate DC power sources and includes a split bus assembly that ensures a continuous supply from a first generator until after a second generator has begun to supply power to the electrical system. Once the second generator is on line the first generator can be shut down. The system can be used when switching between different on-board power supplies or when switching between on-board and external power supplies.    ADVANTAGE -   Ensures continuous power supply during changeover from one power source to another, lightweight, compact, and low cost.
