Abstract:
1. An apparatus comprising: a first node to supply power received from a power source, the first node having an associated first operating impedance; a second node to receive power to be supplied to a load separate from the power source, the second node having an associated second operating impedance; and a power extractor to transfer power from the first node to the second node, wherein the power extractor is operated such that an input impedance of the power extractor, in relation to the first operating impedance, and an output impedance of the power extractor, in relation to the second operating impedance, are each to be adjusted based, at least in part, on both the load and the source, including wherein voltage and current at the first node are not fixed and the power transferred to the second node is unregulated with respect to the load.
