Abstract
Methods for storing electrical energy discharged from a capacitive source, embodiments including developing a capacitive load in the source and closing a switch between the capacitive source and a voltage conversion block after an output voltage of the source both exceeds a threshold value and is detected to peak. The conversion block includes an inductor and the storage device connected in series and further may include a diode connected in parallel across the inductor and the storage device. Apparatus for storing electrical energy discharged from a capacitive source include embodiments having a capacitive source configured to produce an output voltage, a switch connected to the source, an inductor connected to the switch, a storage device connected to the inductor and a controller configured to close the switch after an output voltage of the source both exceeds a threshold value and is detected to peak.
