Abstract
A system and method thereof to regulate a current to a capacitive load from a power supply connected to the capacitive load. The system includes a first switch between the power supply and the capacitive load, 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, a second switch between the super-capacitor and the capacitive load, 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.
