In this paper, an Adaptive Multi-Phases Converter is used to improve the efficiency and reliability of a photovoltaic power conversion chain. We present a control law which adapts the number of converter according to the power production and guarantees also high conversion efficiency, even in the presence of a constantly changing operating point, which is the principal characteristic of a photovoltaic system. The second control law consists in the rotation of phases of the converter. This rotation guarantees a homogeneous work time, increasing the average life time of the converter. Experimental test has shown the performance of this structure.
