  • System for improving lightning immunity for a solid state power controller
    Patent number: 9590412
    Abstract: A solid state power controller (SSPC) for an electrical power distribution system (EPDS), the SSPC may include a solid state switching device (SSSD) configured to interrupt current in a feeder line of the EPDS and a processing engine. A clamping device may be interposed between the feeder line and an electrical ground of the EPDS, An opto-coupler may be interposed between the processing engine and the clamping device. The opto-coupler may coupled to the clamping device to provide a lightning-detected signal to the processing engine only when a voltage drop develops across the clamping device. The processing engine may be constrained from commanding an alteration of state of the SSSD upon receiving the lightning-detected signal.
    Type: Grant
