Patent ID: 8716997

Claim:
A solid state power controller (SSPC) comprising: a pre-charge circuit connected in parallel with a solid state switching device, wherein the pre-charge circuit includes: a MOSFET receiving power from a main power bus at an input side of the solid state switching device; an inductor in series with the MOSFET and to a load side of the solid state switching device; and a freewheeling diode connected between the MOSFET and the inductor; and a gate driver integral to a DSP control engine of the power controller, the gate driver coupled to the MOSFET and configured to control a switch of the MOSFET of the pre-charge circuit in a pulse width modulation fashion based on a sampled load voltage measurement to apply an on logic to the MOSFET until the sampled load voltage reaches an input voltage of the SSPC and to apply an off logic to the MOSFET when the sampled load voltage reaches the input voltage of the SSPC.
