APPARATUS AND METHOD FOR EXTRACTING MAXIMUM POWER FROM ENERGY HARVESTER APPARATUS
First Claim
1. A method for extracting maximum power from an energy harvester apparatus, the method comprising:
- detecting, by an apparatus for extracting maximum power disposed between the energy harvest apparatus and an energy storage apparatus, a magnitude in output current flowing in the energy storage apparatus;
comparing a magnitude in current extracted from the energy harvester apparatus with a magnitude in current supplied to the energy storage apparatus when the magnitude in output current is a positive number; and
determining whether an algorithm for extracting maximum power using the magnitude in current based on the comparison result is applied and extracting the maximum power depending on the determination result.

Abstract
An apparatus and a method capable of maximally transferring energy generated from an energy harvester apparatus to an output terminal by optimizing an input impedance of an apparatus for extracting maximum power disposed between an energy harvester apparatus and an energy storage apparatus are disclosed. The method for extracting maximum power includes: detecting, by an apparatus for extracting maximum power disposed between the energy harvest apparatus and an energy storage apparatus, a magnitude in output current flowing in the energy storage apparatus; comparing a magnitude in current extracted from the energy harvester apparatus with a magnitude in current supplied to the energy storage apparatus when the magnitude in output current is a positive number; and determining whether an algorithm for extracting maximum power using the magnitude in current based on the comparison result is applied and extracting the maximum power depending on the determination result.
