This paper presents a novel grid-connected boost-full-bridge photovoltaic (PV) micro-inverter system and its control implementations. The concept of micro-inverter is a future trend for grid connected Photovoltaic micro-inverter. Increasing demand on the renewable energy sources has made the grid connected inverter systems to be more important than ever before. Maximum Power Point Tracking (MPPT) technique is implemented which is used by the grid connected inverters to get the maximum possible

Interleaving of the Boost DC-DC converter is carried out to get more boost up voltage and better efficiency. A new multilevel inverter topology constituting of a H-bridge structure with four switches connected to the dc link. Based on Phase Opposition Disposition technique a new PWM method requires only one carrier signal is suggested.
