Abstract
A power distribution system includes a solid state power controller (SSPC). The SSPC includes a microcontroller having at least one voltage sense input. The microcontroller is configured to selectively allow a current through the SSPC in response to a common mode voltage to ground and/or a SSPC differential voltage meeting or exceeding a respective pre-determined threshold. A method of operating a SSPC includes determining whether at least one of a common mode voltage to ground or a SSPC differential voltage meet or exceed a respective pre-determined threshold. The method includes selectively allowing a current through the SSPC in response to at least one of the common mode voltage to ground or the SSPC differential voltage meeting or exceeding the respective pre-determined threshold.
