Abstract

In    this    paper,    an    Adaptive    Multi-PhasesConverter  (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.
