Solid state power controller gate control

摘要

A system for controlling gate power includes a metal oxide semiconductor field effect transistor (MOSFET) configured to supply power to a load according to a gate control voltage applied to a gate of the MOSFET. The system includes a gate control circuit configured to turn on and off the gate control voltage supplied to the gate of the MOSFET. The system also includes a ramping circuit configured to perform at least one of ramping up a voltage applied to the gate of the MOSFET based on the gate control circuit turning on power to the gate of the MOSFET and ramping down the voltage applied to the gate of the MOSFET based on the gate control circuit turning off power to the gate of the MOSFET.
