Abstract

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.
