This paper makes a comparative investigation of the three basic non-isolated dc-dc converters used as interface for maximum power point tracking (MPPT) application in photovoltaic generators using the direct duty ratio control tracking algorithm. Analysis of the buck, boost, and buck-boost converters has been undertaken to study the behavior of the converter's performance with respect to the changing atmospheric conditions and in-turn duty ratio variation (as a result of MPPT) and the tracking efficiency of each converter. Effect of different resistive loads on the output of the converter side has also been considered for the three topologies and it has been observed that the buck-boost converter is the only converter which is able to track the maximum power point under variation of insolation, temperature, and loading effect, with the highest tracking efficiency.
