1. An energy harvesting device comprising:
a current transformer in electrical communication with an electrical conductor and configured to harvest electrical energy from the electrical conductor by converting magnetic flux generated by the flow of alternating current though the electrical conductor into a first current;
a voltage clamping circuit configured to receive the first current and produce a first voltage at a clamped voltage level;
a supplementary voltage regulator separate from the voltage clamping circuit, and configured to operate continuously to maximize the harvested electrical energy by adjusting the clamped voltage level.
