In this paper, an improved power conversion structure for integrating photovoltaic systems into the power grid is presented. In order to obtain a galvanic insulation between the grid and the PV panel, many PV systems use a power transformer, avoiding that a leakage current may flow through the capacitance between PV panel and ground. Some systems use a transformer embedded in a high-freq ency DC/DC converter. This structure is based on a multilevel inverter and on an isolated DC-DC converter. The structural design of this power converter allows a nine-level shaped output voltage wave at the output of the multilevel inverter. To control the proposed structure, model predictive control(MPC) technique is used. PSCAD/EMTDC software is used for simulation of the converter
