An apparatus for obtaining information enabling a characteristic like determination of maximum power point of a power source, the apparatus including at least an inductor and a capacitor, the information enabling the determination of the characteristic of the power source being obtained by monitoring the voltage charge of the capacitor, and a mechanism discharging the capacitor through the inductor prior to the monitoring of the charge of the capacitor.

Method for obtaining information enabling the determination of a characteristic of a power source

The present invention concerns an apparatus for obtaining information enabling the determination of a characteristic like the maximum power point of a power source, characterized in that the apparatus for obtaining information enabling the determination of the characteristic of the power source comprises means for monitoring the voltage on an inductor linked to the power source in order to obtain information enabling the determination of the characteristic of the power source.

A method and apparatus for controlling the output voltage of a boost converter including a number n of bridge devices connected in series, each bridge device including plural switches and a capacitor. The method and apparatus provide control of the switches according to a selected periodical matrix pattern including a number N of time intervals, N being a positive integer greater than 2, and in that in each time interval, the voltage between the input and the output of each ith bridge device with i from one to n, is equal to one of a null value, a number ki times a positive value, and minus the number ki times the positive value, the positive value being the result of the division of the output voltage of the boost converter including the n bridge devices by the number of time intervals N of the periodical matrix pattern.
