  • Patent number: 12220992
    Abstract: A system comprises: one or more point-of-use controllers configured to: assert a command-on signal to load a first turn-on gate driver profile; control, based on the loaded first turn-on gate driver profile, a gate driver to begin a first phase of a turn-on operation; receive a first power switch signal based on one or more of a detected voltage or a detected current; perform a comparison of the received first power switch signal to a first turn-on threshold value; load a second gate turn-on driver profile when the comparison indicates the first power switch signal is greater than the first turn-on threshold value; and control, based on the loaded second turn-on gate driver profile, the gate driver to end the first phase of the turn-on operation and begin a second phase of the turn-on operation.
