摘要： A method and system for a control power supply system is provided. The control power supply system includes a first conductor configured to carry a direct current (DC) electrical current from a source to a load, a second conductor configured to carry the DC electrical current from the load to the source, a electrical device electrically coupled in series with at least one of the first and second conductor. The electrical device is configured to fail in a shorted condition such that failure of the electrical device maintains a direct current (DC) ring bus including the first and second conductor. The control power supply system also includes a control power circuit electrically coupled in parallel with at least a portion of the electrical device such that a DC voltage across at least a portion of the electrical device provides a DC voltage supply to the control power circuit.
