Abstract: Usually due to the unique characteristics of solar cells, they are not connected directly to the load. Instead a dc/dc converter is used as the interface between the solar panel and load. Low output voltage and high output current are some features of photovoltaic sources. Therefore, a converter that is inserted as the interface between the solar panel and load must be compatible with these features. Current-fed converters are compatible with characteristics of photovoltaic sources. Present thesis uses a current-fed dc/dc converter with an advantage of the interleaved technique for increasing the voltage. The converter must be controlled so that a solar cell operation point always to be put on the maximum power point. This is done by the MPPT algorithm. For tracking the maximum power point current research uses a MPPT algorithm based on incremental conductance. In this way, dynamic deviations are measured to speed up the maximum power point tracking. The results of the algorithm simulation on dc/dc converter represent efficiency of this method.
