The grid-connected photovoltaic (PV) system is an important technology for renewable energy applications. It usually consists of three main stages: a PV module, a DC/DC converter and a DC/AC inverter. In these PV systems, Power Conditioning System should have high efficiency and low cost. In this paper, a classification of possible power converter topologies for PV panel integration is introduced. Out of different topologies of DC/DC converter, series connection of boost converters is more suitable converter for PV applications. In order to simulate the steady state efficiencies of the series connection of boost converters and the inverter non-ideal averaged model of these power converters is developed. Then the different elements and control of the (PV) system are implemented in Matlab/Simulink. Using loss analysis, the benefits and drawbacks of series connection of boost converters are shown. This analysis allowed the conception of an optimized architecture constituted by serialized power converters. [ABSTRACT FROM AUTHOR]
