Claim Text:
1. A method comprising: recovering and regenerating a leakage current from a first capacitor having a first electrode and a second electrode, by applying a voltage to the first capacitor through a first switch selectively connected to a charging voltage and the second electrode of the first capacitor; storing charge corresponding to the applied voltage in the first capacitor; controlling a second switch to allow a leakage current to flow from the first capacitor to a second capacitor, the second switch being selectively connected to the second electrode of the first capacitor and to the second capacitor; storing charge corresponding to the leakage current of the first capacitor in the second capacitor; and controlling a third switch to allow charge from the second capacitor that corresponds to the leakage current of the first capacitor to flow back to the first capacitor to increase the efficiency and enhance the performance of the first capacitor.
