Embodiment Construction

[0035] exist figure 1 , a first embodiment of the system is shown. The system comprises a controller 1 for controlling a converter 2 configured to convert a first power from a solar device 3 into a second power for a battery device 4 . Furthermore, the terminals of the solar device 3 are coupled to the first and second terminals 26 , 27 of the converter 2 and the third and fourth terminals 28 , 29 of the converter 2 are coupled to the terminals of the battery device 4 . Converter 2 includes an input capacitor 21 coupled to first and second terminals 26 , 27 of converter 2 and includes an output capacitor 25 coupled to third and fourth terminals 28 , 29 of converter 2 . A first terminal 26 of converter 2 is coupled to a third terminal 28 of converter 2 via a first switch 22 , such as for example a first transistor, and via an inductor 24 . The interconnection between the first switch 22 and the inductor 24 is coupled to the second and fourth terminals 27, 29 of the converter ...

Abstract

Controllers (1) control converters (2) that convert first power from solar arrangements (3) into second power for battery arrangements (4). The control comprises, in response to detections of values of current signals flowing through the battery arrangements (4), adjustments of impedances of the converters (2) for maximizing the current signals. A kind of maximum power point tracking is performed, without many multiplications of voltage signals and current signals provided by the solar arrangements (3) needing to be performed. The adjustments may comprise adjustments in first directions in case the values of the current signals flowing through the battery arrangements (4) show increases and adjustments in different second directions in case the values of the current signals flowing through the battery arrangements (4) show decreases. The adjustments may comprise adaptations of pulse width modulations of the converters (2).
