Abstract:
1. A system for harvesting energy from an alternating magnetic field comprising: a flux concentrator having an open core coil wherein a first current with a first voltage can be induced in the flux concentrator when placed proximate an alternating magnetic field; a transformer, having a first winding and a second winding, connected to the flux concentrator and enabled to induce a second current in the second winding, wherein the second current has a second voltage higher than the first voltage and higher than a threshold voltage of a first diode and a second diode; a converter configured to selectively connect a short circuit between the secondary winding and the converter to charge the leakage inductance of the secondary winding; and the first diode and the second diode connected to the secondary winding and the converter for discharging the leakage inductance.
