Systems And Methods For Providing AC/DC Boost Converters For Energy Harvesting

A method for harvesting energy from an alternating magnetic field comprising:

• placing a system for harvesting energy having a transformer proximate the alternating magnetic field;
• inducing, from the alternating magnetic field, a first current having a first voltage on the transformer;
• inducing a second current having a second voltage with the transformer having a first and second winding, wherein the second voltage is higher than the first voltage and a diode threshold voltage of an output diode;
• charging a leakage inductance in the secondary winding by creating a connection between an output of the secondary winding and an input of the secondary winding;
• and
• discharging the leakage inductance in the secondary winding by disconnecting the connection between the output of the secondary winding and the input of the secondary winding.

A system for harvesting energy from an alternating magnetic field comprising:

• a current-carrying asset;
• a first alternating current flowing through the current-carrying asset and creating the alternating magnetic field;
• an open core coil proximate to the current-carrying asset wherein a second alternating current with a first voltage is induced in the open core coil from the alternating magnetic field;
• a transformer for inducing a third alternating current with a second voltage;
• a converter connected to the transformer for selectively connecting an output terminal of the transformer with an input terminal of the transformer;
• a first output diode and a second output diode connected to the converter and the transformer;
• an astable multivibrator producing a clock signal and connected to the converter and the first and second output diode;
• and
• a sensing circuit for taking measurements and transmitting the measurements wirelessly;
• wherein the second voltage is higher than a threshold voltage of the first diode and the second diode.
