CPC H02J 50/001 (2020.01) [H01F 38/14 (2013.01); H02J 50/10 (2016.02); H02M 7/219 (2013.01)] | 26 Claims |
1. An assembly for harvesting power from one or more power cables, the assembly comprising:
a current transformer with an active burden load, the current transformer to harvest power from the one or more power cables and output the harvested power as alternating current;
a rectifier connected to the current transformer in parallel with the active burden load, the rectifier to receive the alternating current from the current transformer and output direct current;
a controller to send a load control signal to the current transformer, the current transformer to modify the active burden load based on an amount of load encoded in the load control signal;
an input monitor to monitor the direct current output by the rectifier and send an input signal to the controller encoding at least one first property of the direct current output by the rectifier;
a converter to receive the direct current and output electricity to a load, the controller to send an output signal to the converter encoding an amount of electrical output, the converter to output the electricity in accordance with the output signal; and
an output monitor to encode, as an output load signal, at least one second property of the electricity after the electricity passes through the load and send the output load signal to the controller, the controller to determine the amount of electrical output and the amount of load based on the input signal and the output load signal, the controller to encode the amount of electrical output in the output signal, and to encode the amount of load in the load control signal.
