In this paper, a new inverter topology dedicated to isolated or
grid-connected PV systems is proposed. This inverter is based on the structures
of a stacked multi-cell converter (SMC) and an H-bridge. This new topology has
allowed the voltage stresses of the converter to be distributed among several
switching cells. Secondly, divide the input voltage into several fractions to
reduce the number of power semiconductors to be switched. In this contribution,
the general topology of this micro-inverter has been described and the
simulation tests developed to validate its operation have been presented.
Finally, we discussed the simulation results, the efficiency of this topology
and the feasibility of its use in a grid-connected photovoltaic production
system.
