Abstract

In this paper, an Adaptive Multi-Phases Converter (AMPC) is used as an adaptation stage to improve the efficiency and reliability of a photovoltaic power conversion chain. We present a control law which guarantees high conversion efficiency, even in the presence of constantly changing operating point which is principal characteristic of the photovoltaic system . Another control law which consists in the rotations of phases of the converter is also presented. This rotation guarantees a homogeneous aging, increasing the average life time of the converter. Guidelines of these control laws are presented. An experimental prototype has been designed to evaluate the performances of this proposed adaptation stage.
