A parasitic diode (Dp) which the MOSFET (T2) comprises is provided in such a manner that the direction opposite to the direction of a load current (ID) is the forward direction thereof.

The solar cells (10) are arranged with the direction of electricity conduction aligned in a matrix form having eight rows and four columns.

Said reference diode (D1; D2) is arranged in the direction of passage between the supply potential (Vdd; Vss) and the serial resistor (R1).

Two series-connected valve branches of this type having opposite conduction directions bypass two series-connected current limiter inductors.

According to the invention, the conductor elements (L11 to L41; L12 to L42) that are disposed on the opposite flat faces in parallel have the same current direction.

Each component (7) has at least two of the dipoles, at least one of which is configured as a rectifier, the current of which flows towards the cathode (16).

A controllable voltage source can be connected in series in relation to the valve in the respective forward direction of the valve and in said circles.

Circles are produced by an inductor and a valve.
