Pre-charge circuitry allows capacitive loads connected to a solid state power controller to be gradually charged up by a PWM, generated with a cycle by cycle current limit, switching a single MOSFET in series with an inductor, before the SSPC is turned on. The pre-charge circuitry may require only three additional components, e.g., a MOSFET, an inductor and a diode, along with a designated MOSFET gate driver.

High power DC SSPC with capability of soft turn-on large capacitive loads

A power distribution system includes the use of a master digital signal processor (DSP) and two slave DSPs connected to the master DSP. The slaves DSPs may be connected to each of a plurality of solid state power channels (SSPC) controlling power distribution functions to each of the channels. A power control strategy may use one power supply for the master DSP, a second power supply shared between the slave DSPs, and a third power supply shared between each of the SSPC channels.
