Claim:
1. A solid-state power controller system comprising: a power source comprising a plurality of output channels comprising a first output channel and a second output channel; a first solid-state power controller comprising a first sharing control FET, wherein the first sharing control FET is coupled in series along the first output channel; a second solid-state power controller comprising a second sharing control FET, wherein the second sharing control FET is coupled in series along the second output channel; and a controller in electrical communication with the first solid-state power controller and the second solid-state power controller; a sense resistor coupled in series with the first output channel; and a balance resistor coupled in parallel with the first sharing control FET, wherein the controller directs the operation of a gate of the first sharing control FET and a gate of the second sharing control FET via one or more control algorithms, the first sharing FET is configured to be in an OFF state while the first solid-state power controller is toggled to an ON state and directs sharing control for in-rush currents through the balance resistor, and a control loop algorithm configured to toggle the first sharing FET to an ON status and operate the first sharing FET in a linear region during normal ON operation of the first solid-state power controller.
