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 implement a test-the-tester process to:
- transmit, to a power receiver, a command for the power receiver to introduce a calibrated reference load;
- sample, by a transmitter-side current sensing circuit, a current in a hybrid cable coupled to the power transmitter and the power receiver, wherein the current in the hybrid cable is also sampled synchronously by a receiver-side current sensing circuit included in the power receiver;
- encode first data corresponding to the current sampled by the transmitter-side current sensing circuit;
- receive, from the power receiver, second data corresponding to the current sampled by the receiver-side current sensing circuit;
- compare the first data and the second data to determine a difference in the current sampled by the transmitter-side current sensing circuit and the current sampled by the receiver-side current sensing circuit;
- and
- determine whether the difference is within a predetermined tolerance.

A power receiver included in a fault-management power system, the power receiver 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 implement a test-the-tester process to:
- receive, from a power transmitter, a command for the power receiver to introduce a calibrated reference load;
- couple the calibrated reference load to a receiver-side current sensing circuit;
- sample, by the receiver-side current sensing circuit, a current in a hybrid cable coupled to the power transmitter and the power receiver, wherein the current in the hybrid cable is also sampled synchronously by a transmitter-side current sensing circuit included in the power transmitter;
- encode first data corresponding to the current sampled by the receiver-side current sensing circuit;
- receive, from the power transmitter, second data corresponding to the current sampled by the transmitter-side current sensing circuit;
- compare the first data and the second data to determine a difference in the current sampled by the transmitter-side current sensing circuit and the current sampled by the receiver-side current sensing circuit;
- and
- determine whether the difference is within a predetermined tolerance.
