Abstract
A solution is disclosed for providing fault-managed power systems using optical elements. The fault-managed power systems are able to provide safe and efficient power delivery utilizing optical fiber links to improve signal integrity, security, and reach of the system.
Claims20
A power transmitter included in a fault-management power system, the power transmitter comprising:
- a processor;
- and
- a memory in communication with the processor, the memory including executable instructions that, when executed by the processor, causes the processor to:
- control a power switch to disconnect the power transmitter from a power source during a system initialization mode;
- control a low power switch to connect to a low power source and power an optical subassembly;
- determine a predetermined condition of whether at least one optical fiber port and at least one electrical port is connected to a hybrid cable, and control an optical data interface to transmit a connection request to a power receiver based on the determination;
- receive, by the optical subassembly, a reply to the connection request from the power receiver, the reply being transmitted over an optical fiber included in a hybrid cable;
- receive, by the optical subassembly, a diagnostic message from the power receiver, the diagnostic message being transmitted over the optical fiber included in the hybrid cable;
- conduct a fault detection test;
- determine whether a power transmission condition is met based on at least the diagnostic message and the fault detection test;
- and
- control transmission of high voltage power to the power receiver based on the determination, the high voltage power being transmitted over a conductor wire included in the hybrid cable.
