Abstract
(A1) Vorgestellt wird eine Anpassschaltung fuer in einem Stromkreis in Reihe geschaltete Solarzellen oder in Reihe geschaltete Gruppen von Solarzellen (SM) unter Verwendung eines Gleichspannungswandlers (B), wobei im Gleichspannungswandler (B) eine Schalteinrichtung (S1) vorhanden ist, die zur Gleichspannungswandlung getaktet werden muss, wobei eine Steuerung (St) zur Ansteuerung der Schalteinrichtung (S1) vorhanden ist. Die Anpassschaltung zeichnet sich dadurch aus, dass die Steuerung (St) so ausgestaltet ist, dass bei der Taktung Verluste des Gleichspannungswandlers (B) beruecksichtigt werden. Die Erfindung betrifft auch ein zugehoeriges Verfahren.

 

DE 102009051186 A1 UPAB: 20100520 NOVELTY - The circuit has a direct current/direct current converter (B) with a switching device (S1) that is synchronized to direct current conversions. A controller (St) controls the switching device, where the controller is designed in such a manner that the direct current/direct current converter is taken into account during timing loss. A solar cell or a group of solar cells (SM) is attached on inputs (3, 4) of the direct current/direct current converter, where the solar cell or a group of solar cells is operated in a predetermined operating region or operating point. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a solar generator comprising a solar module (2) a method for controlling a direct current/direct current converter. USE - Matching circuit for use in a solar generator for an electric system in a series-connected solar cell or series-connected group of solar cells using a direct current/direct current converter (all claimed). ADVANTAGE - The circuit is designed in such a manner that the current is transmitted from the solar module into the direct current/direct current converter without any loss when the direct current/direct current converter is not operated.
