<p>A system for managing AC energy harvested from a harvesting device (1) including a coil (4) including switching circuitry (S1-S4) coupled between first (7A) and second (7B) terminals of the coil. The switching circuitry includes first (S1), second (S2), third (S1), and fourth (S4) switches. A switch controller (17) closes the second and fourth switches to allow build-up of current (ILh) in the coil, opens one of the second and fourth switches, and closes a corresponding one of the third and first switches in response to the built-up inductor current reaching a predetermined threshold value (Ihrv) to steer the built-up inductor current through the corresponding one of the third and first switches to a current-receiving device (24 and/or RL,CL).</p> |
