Definitions
- the diode matrix circuit is preferably designed such that the solar elements are connected to one another as an m ⁇ n matrix, as described above, and can be interconnected in different arrangements.
- the matrix may be formed as a 3 x 3 matrix.
- the diode matrix circuit has the advantage that a dynamic interconnection of the solar elements can take place, wherein the interconnection or a change in the interconnection preferably takes place automatically by means of the diodes controlled by the voltage of the solar elements, without the intervention of a control unit being absolutely necessary. This offers the advantage that the dynamic interconnection can be carried out particularly efficiently and in particular in a passive manner.
- Fig. 6 shows a solar generator with parallel solar cell strings, thereof a string shortened electrically
- Solar modules consist of a series connection of solar cells.
- Solar cells are not voltage but current sources.
- a solar cell provides a Lichtein radiation proportional electrical current.
- Ideal current sources have an infinitely high output voltage According to the usual rules of electrical engineering, one would have to switch parallel current sources.
- the solar cells have only a low real output voltage of about 0.6 V at the maximum power point (MPP), they are still connected in series (as a string) in order to achieve technically usable input voltages.
- the output voltage of such a series circuit from solar cells may currently be up to 1500 VDC.
- Each power bus requires an MPPT because the number of cells in a power bus group varies with the lighting and the bus voltage is different and variable.
- Each solar cell can be connected in series to one of the power buses. With complete freedom of choice for the connection to power buses, the number of required switches or MPPTs is high.
- FIG. 31 shows a circuit of cell strings or strings 26a, 26b, 26c according to a preferred embodiment.
- the strands 26b and 26c are connected in series in such a way that they form one arm of a parallel circuit.
- the strand 26c and a diode D4 are connected in series.
- such a circuit is realized with a pole changing circuit and / or a diode matrix circuit.
- This circuit has the advantage that diodes with one or more strings can be connected in series and in this way strands of different lengths or with a different number of Solar cells can be connected in parallel, without disadvantageous balancing currents arise.

Abstract
L'invention concerne un agencement de plusieurs éléments solaires comportant plusieurs commutateurs. Les commutateurs peuvent interconnecter de diverses manières les éléments solaires selon différents agencements électriques de manière dynamique pendant le fonctionnement. L'invention concerne en outre un procédé d'interconnexion d'éléments solaires au moyen de commutateurs. Un ombrage ou une différence de puissance entre différents éléments solaires est détectée et les éléments solaires sont classés en différents groupes en fonction de leurs puissances actuelles ou de leur puissance maximale actuellement possible ou de l'état d'éclairage actuelle et les éléments solaires de chaque groupe sont interconnectés.
