The invention relates to a conditioning circuit that measures operating points
of a power supply to deduce therefrom the current-voltage characteristic thereof
and to determine directly the voltage corresponding to its maximum power point,
without using any kind of tracking algorithm that causes the operating point of
the power unit to oscillate about the maximum power point. The maximum power point
voltage VMPP is supplied to a controller which regulates a power cell by slaving
it to the input voltage until the output voltage of the supply is equal to the
maximum power point voltage VMPP. The invention also relates to a solar
generator and an associated conditioning method. One particular application is
to high-power satellites.
