© 2016 IEEE. In the recent years growing interest has been given to photovoltaic (PV) microinverters. Sub-modular optimization of PV panels where the junction-box of the panel is removed and each sub-modules is connected to an individual DC-DC converter realizing independent MPPT is one promising solution especially for systems subject to partial shading. In this paper, individual flyback DC-DC converters are considered to realize the MPPT as well as the voltage elevation required for grid connection of a microinverter. This paper aims to show the interest of using cascaded H-bridges for realizing the DC-AC conversion, compared with a single H-bridge inverter. Simulation results are provide to show the improvement realized by using cascaded H-bridge inverters in a sub-module microinverter architecture, both in term of efficiency and power quality.
