Claim:
1. A system to regulate a current to a capacitive load from a power supply connected to the capacitive load, the system comprising: a first switch between the power supply and the capacitive load, electrically connecting the capacitive load to the power supply in a closed position thereof, and electrically disconnecting the capacitive load from the power supply in an open position thereof; a super-capacitor configured for charging by the power supply and powering the capacitive load; a current limiting circuit between the super-capacitor and the power supply, electrically connecting the super-capacitor to the power supply in a closed position thereof, and electrically disconnecting the super-capacitor from the power supply in an open position thereof; a second switch between the super-capacitor and the capacitive load, electrically connecting the super-capacitor to the capacitive load in a closed position thereof, and electrically disconnecting the super-capacitor from the capacitive load in an open position thereof; and a power control circuit configured to control opening and closing of the first switch and the second switch independently, sense a voltage of the power supply, and sense a voltage of the super-capacitor.
