New Topology of Photovoltaic Microinverter based on Boost converter

This paper proposes a new microinverter topology dedicated to photovoltaic off-grid systems or connected to the grid. This Microinverter is based on simple boost with high gain in the aim of a reduction of the total number of active components allowing, thus a high efficiency conversion. In a first part of this contribution, we describe the general topology of this micro-inverter and present the simulation tests developed in order to validate its functioning. Finally, the last part is dedicated for discussion of the simulation results, the efficiency of this topology and the feasability of its used in a photovoltaic generation system connected to the grid.
