1	Maximum Power Point Tracking Method and Tracker Thereof for a Solar Power System	A maximum power point tracking method and a tracker thereof for a solar power system comprises the steps of: connecting a DC/DC converter to a solar cell; a controller acting the DC/DC converter as a power converter with an active resistance characteristic for supplying power to a DC/AC converter or a DC load; the maximum power point tracking circuit adjusting the DC/DC converter in a direction for changing the active resistance; abserving a change in output power o the solar cell; continuously adjusting the DC/DC converter in the same direction for continuously adjusting the DC/DC converter in the same direction for continuously changing the active resistance if receiving a positive change in the output power o the solar cell, atlernatively, adjusting the DC/DC converter in a reversed direction if receiving a negative change in the output power of the solar cell; the maximum power point tracking circuit repeatedly adjusting the DC/DC converter in the same or reversed direction for searching a maximum power point of the power output of the solar cell, and successively adjusting positions of the DC/DC converter to locate around the maximum power point.
