Abstract: Techniques are described to harvest power from a single current carrying conductor to furnish power to a powered device. The techniques employ a power harvesting device that is coupled to the conductor. In implementations, the conductor has a first path and a second path. The power harvesting device includes a first switch coupled to the second path. An energy storing element is coupled to the first path and configured to store energy based upon the direct current flowing through the first path. The power harvesting device also includes a power condition and management device coupled to the energy storing element configured to switch the first switch to a closed configuration when the energy storing element is measured to have a predefined high voltage threshold, and to switch the first switch to an open configuration when the energy storing element is measured to have a predefined low voltage threshold.
