Patent ID: 8446132

Claim:
A power conversion circuit, comprising: a current monitor operably coupled to a power source signal for operable coupling to a power delivery element and configured for generating a source current indicator; a controller configured to generate a control signal responsive to the source current indicator; a filter well with an input side operably coupled to the power source signal; an inductive switch circuit configured for switchably grounding a rectified inductive load coupled to an output side of the filter well responsive to the control signal to develop a pulsed power signal; and a resonance rectifier configured to present a substantially lossless resistive impedance for the pulsed power signal and rectify the pulsed power signal to charge a charge storage device and generate a power output signal; wherein the filter well, the inductive switch circuit, and the controller are configured to maintain the source current indicator within a predetermined current range by filtering the pulsed power signal and adjusting at least one of a frequency and a pulse width modulation of the control signal responsive to the source current indicator.
