This paper is about a PV system linked to the electric
grid by power electronic converters. The modeling for the
converters emulates the association of a DC-DC boost with a twolevel
power inverter in order to follow the performance of a
testing commercial inverter employed on an experimental system.
It is used pulse width modulation by sliding mode control
associated with space vector modulation for control the boost and
the inverter. The PV system is described by the five parameters
equivalent circuit and parameter identification is carried out.
Maximum power point tracking is implemented by
a P V procedure. Simulation studies are performed and a
comparison with the testing experimental system is presented
