Title:
MAXIMUM POWER POINT TRACKING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/087342
Kind Code:
A2
Abstract:
The present invention relates to a maximum power point tracking method, comprising the following steps: temporarily determining a next voltage instruction value using the voltage and electric power measured at a current measuring time and at a previous measuring time; finally determining, if the number of times a continuous increase or continuous decrease in the voltage instruction value occurs is larger than a predetermined number of times, that the next voltage instruction value, which is temporarily determined to be increased, is to be decreased, and the next voltage instruction value, which is temporarily determined to be decreased, is to be increased; and adjusting an output voltage of a solar cell in accordance with the finally determined next voltage instruction value.
