Abstract:
An electrical energy regulator system for a power supply bus connected to a load network using an electrical energy, said system including:an electrical energy storage unit, a solar generator comprising a plurality of cells, for each of said cells, means for regulating the power supply voltage of said bus adapted to impose on said cell one of the following three operating states: a first state in which current from said cell supplies power to said bus, a second state in which current from said cell supplies power to said storage unit, and a third state in which said cell is shunted, said cells being divided by said bus voltage regulator means into:a first group in which at least one of said cells supplies power to said bus and one of said cells referred to as a bus voltage regulator cell is assigned to regulation of the voltage of said bus and to this end is in its first state only when maintaining a nominal bus voltage requires a top-up of current from said cell, and a second group in which at least one of said cells is either in a second state or in a third state, as a function of a required charging current of said storage unit, the number of cells in the second state being a function of the required charging current, wherein said system further includes means for regulating the charging of said storage unit which assign at least one of said cells of said second group to supplying power to said storage unit and one of said cells, referred to as a storage unit charging regulator cell, to regulation of the voltage of said storage unit, to which end said storage unit charging voltage regulator cell is in its second state only when maintaining a nominal charging voltage of the storage unit requires a top-up of current from said cell.
