Abstract
A maximum power point tracking method is provided. The method includes temporarily determining a next voltage command using voltage and power measured at current and previous time points. When an increase or decrease in voltage command is continued predetermined times or more, it is decided that the next voltage command temporarily determined to be increased is decreased or that the next voltage command temporarily determined to be decreased is increased. The output voltage of a solar cell is regulated based on the decided next voltage command.
