Abstract
A power control system includes a first switch configured to receive electrical power from a power source and selectably provide the electrical power to a load. A current limiter is intermediate the first switch and the load. A second switch is also configured to receive electrical power from the power source and selectably provide electrical power to the load. The power control system includes a soft-start operating mode wherein the first switch is activated to provide the electrical power to the load, current provided to the load being limited by the current limiter. The second switch is also activated to provide the electrical power to the load, the second switch being activated a predetermined period of time after activation of the first switch. The first and second switches are also deactivated while the voltage of the power source exceeds a predetermined level.
