A power supply system for use with a component comprises at least three phases of power supply, with each of said three phases passing through a solid state power controller having an on/off switch. Each of the phases of power pass through a current sense transformer. A ground fault circuit receives an outlet from the current sense transformer. The ground fault circuit includes an analog filter connected into a digital processor. An output of the digital processor is operable to control the switches on the solid state power controllers. The three phases distribute power to the component when the switch on their associated solid state power converter is on.
