Abstract
A maximum power point tracking circuit, including a capacitive element coupled in parallel with a power source and controlled by a switch to be periodically integrally discharged towards a power transfer stage, wherein, for each switching cycle of the switch, the latter is turned on at a time which is a function of the charge current of the capacitive element at the previous turning-off of the switch.

A maximum power point tracking circuit, comprising a capacitive element coupled in parallel with a power source and controlled by a switch to be periodically integrally discharged towards a power transfer stage, wherein, for each switching cycle of the switch, the latter is turned on at a time which is a function of the charge current of the capacitive element at the previous turning-off of the switch.
A maximum power point tracking method, wherein:
- a capacitive element, coupled in parallel with a power source, is, at each cycle, integrally discharged by power transfer towards a load;
- information representative of the charge current of the capacitive element is measured at the beginning of each charge cycle;
- and
- said information is compared with a threshold to trigger the end of the charge cycle.
