20090108815 | Energy Capture Circuit - 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. | 04-30-2009 |

20120200278 | METHODS AND APPARATUSES FOR ELECTRICAL PULSE ENERGY CAPTURE - Methods and apparatuses are disclosed for power conversion for fuzes and other electrical power consumers. A current monitor coupled to a power source signal generates a source current indicator. A controller generates a control signal responsive to the source current indicator. A filter well is coupled to the power source signal. An inductive switch circuit switchably grounds a rectified inductive load coupled to an output side of the filter well in response to the control signal, developing a pulsed power signal. A resonance rectifier presents substantially lossless resistive impedance for the pulsed power signal and rectifies the pulsed power signal to charge a charge storage device and generate a power output signal. The filter well, the inductive switch circuit, and the controller maintain the source current indicator within a predetermined current range by filtering the pulsed power signal and adjusting the control signal's frequency responsive to the source current indicator. | 08-09-2012 |
