More Information
Summary:Systems, methods, and devices for aircraft power distribution include a bipolar high voltage direct current source component; an electrical loading component capable of drawing electrical power from the bipolar high voltage direct current source component; a set of switching components configured to selectively couple power from the bipolar high voltage DC source component to the electrical loading and a ground fault interruption component coupled to the set of switching components. The ground fault interruption component is configured to detect a ground fault based on a sensed difference between a current flowing out of the set of switching components and back from the electrical loading component.
