Resetable solid-state fuse

A solid-state fuse, comprising:

• a first power terminal operable to couple the solid-state fuse to one or more first components of a power system;
• a second power terminal operable to couple the solid-state fuse to one or more second components of the power system;
• one or more solid-state switching devices operable to disconnect the first power terminal from the second power terminal;
• a bus operable to conduct at least a portion of a system current, the system current indicative of a current flowing through the power system;
• a bus measurement circuit coupled to the bus, the bus measurement circuit configured to measure a voltage across the bus;
• and
• a controller configured to:
• determine a current slope signal indicative of a current slope of the system current based at least in part on the voltage across the bus;
• and
• control the one or more solid-state switching devices to bidirectionally or unidirectionally disconnect the first power terminal from the second power terminal based at least in part on the current slope signal.

A power system, comprising:

• one or more first components;
• one or more second components;
• at least one solid-state fuse coupled between the one or more first components and the one or more second components, the at least one solid-state fuse comprising:
• a first power terminal operable to couple the solid-state fuse to the one or more first components;
• a second power terminal operable to couple the solid-state fuse to the one or more second components;
• one or more solid-state switching devices operable to disconnect the first power terminal from the second power terminal;
• a bus operable to conduct at least a portion of a system current, the system current indicative of a current flowing through the power system;
• a bus measurement circuit coupled to the bus, the bus measurement circuit configured to measure a voltage across the bus;
• and
• a controller configured to:
• determine a current slope signal indicative of a current slope of the system current based at least in part on the voltage across the bus;
• and
• control the one or more solid-state switching devices to bidirectionally or unidirectionally disconnect the first power terminal from the second power terminal based at least in part on the current slope.
