  • Multi-cellular photovoltaic panel system with DC-DC conversion replicated for groups of cells in series of each panel and photovoltaic panel structure
    Patent number: 8044538
    Abstract: A photovoltaic energy conversion system includes a distributed control structure for groups of cells of each multi-cellular panel, the components of which are entirely physically integrated in the photovoltaic panel. Each multi-cellular photovoltaic panel has a DC bus, supplied in parallel by a plurality of DC-DC converters, each provided with a controller that controls the working point of the photovoltaic cells coupled to the input of the DC-DC converter for a maximum yield of electric power by implementing a relatively simple MPPT algorithm. The controller includes a logic circuit and A/D converters of analog signals representing the input voltage and the input current generated by the group of cells that is coupled to the input of the DC-DC converter and optionally also of the output voltage of the converter, and a relatively simple D/A converter of the drive control signal of the power switch of the DC-DC converter.
