POWER EXTRACTOR DETECTING A POWER CHANGE
First Claim
1. An apparatus comprising:
- a first node and a second node; and
a power extractor to transfer power between the first and second nodes, wherein when the power extractor operates in a first mode, the power extractor is operated such that a magnitude of the power transferred is at least partially dependent on a continuously detected power change, and wherein voltage and current at the first and second nodes are unregulated.

Abstract
In some embodiments, a power extractor operates in a manner to obtain more power transferred from the source to the load than typically is obtained without the power extractor. The power extractor may perform universal impedance matching as this is seen from either the power source or the load. This impedance matching allows the power source to provide an optimal amount of power transfer that is greater than would be able without the impedance matching. The power extractor transfers power between two nodes and may be operated so that the power transferred is dependent on continuously detected power changes, and the voltage and current at the first and second nodes are unregulated. Other embodiments are described and claimed.

26. An apparatus comprising:
-
a first node and a second node; and a power extractor to transfer power between the first and second nodes, wherein the power extractor is to transfer power between the first and second nodes, but does not regulate input voltage or input current at the first node and does not regulate output voltage or output current at the second node, wherein the power extractor includes protection circuitry to regulate power transfer between the first and second node in response to an indication of a limiting condition. - View Dependent Claims (27, 28, 29, 30, 31)

32. An apparatus comprising:
-
a first node and a second node; and a switching converter to transfer power between the first and second nodes, wherein the switching converter is sensitive to changes in power as it is transferred between first and second nodes, and the switching converter continuously operates to seek a maximum power through detecting power slopes and changing the power transferred so that the power slope approaches zero. - View Dependent Claims (33, 34, 35)
