Abstract
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.
Claims10
Apparatus for obtaining information enabling the determination of a maximum power point of a power source, the apparatus comprising:
- at least an inductor and a capacitor connected together via a switch,
- means for monitoring the voltage charge of the capacitor,
- discharging means including the switch for discharging the capacitor through the inductor prior to the monitoring of the voltage charge of the capacitor, and
- means for monitoring the current flowing through the inductor and the switch during the discharge of the capacitor by the discharging means,
- wherein the capacitor is discharged in the inductor by the discharging means as long as the current flowing through the inductor reaches a first predetermined value or as long as the capacitor is not discharged.
Method for obtaining information enabling the determination of a maximum power point of a power source connected to a direct current converter, the direct current converter comprising at least an inductor and a capacitor connected to each other via a switch, the method comprising:
- discharging the capacitor through the inductor via the switch,
- monitoring the voltage charge of the capacitor in order to obtain information enabling the determination of the maximum power point of the power source,
- monitoring the current flowing through the inductor and the switch during the discharge of the capacitor by the discharging the capacitor, and
- wherein the capacitor is discharged in the inductor by the discharging as long as the current flowing through the inductor reaches a first predetermined value or as long as the capacitor is not discharged.
