Abstract
An energy capture circuit for capturing energy in response to an input pulse. The circuit is constructed and arranged to transfer input energy in time divided portions among subcircuits. This includes a storage means, a clock means, at least two subcircuits, and at least one transfer circuit. Each subcircuit includes a first inductive means in operative communication with the input source, a rectifying means for producing a positive current in operative communication with the first inductive means, a capacitive means in operative communication with the rectifying means, and a switch means in operative communication with the capacitive means. At least one transfer circuit is in operative communication with each of the switch means of the at least two subcircuits. The output of the clock means is in operative communication with both a first switch means and an inverter means, the inverter means having an output in operative communication with a second switch means.
