This paper presents a technique for interconnecting a photovoltaic generator (PVG) to a main supply of AC nature. The technique uses a single phase full wave bridge rectifier. Such bridge rectifier is operated in an inverter mode of operation. and that is to guaranty its contribution of real power to a main AC supply. The bridge rectifier is also operated in such a way that its control circuit (i.e triggering circuit) is self adjusted when extracting the maximum power from the PVG and injecting such power into to the main AC supply. The proposed technique has been formulated by a MATLAB/SIMULINK model. The simulation of the developed simulink model shows for a certain pre-defined AC load that up to 66.39 % of the power required by an AC load is obtained from the PVG source. The remaining 33.61 % of power required by the AC load is provided by the main AC supply. The Simulink model shows also that nearly 99.14 % of power can be extracted from the PVG source at a certain pretended solar radiation level (i.e insolation level).
