Abstract
A power converter arrangement with a plurality of d.c voltage inputs of a chronologically varying input voltage, preferably from a solar cell arrangement, is described. In this case, every d.c. voltage input is connected with an associated converter cell, which in turn has at least one step-up converter connected with the input poles, and a recovery diode arranged between the two output poles. Furthermore, the output poles of the converter cells are connected in series and thus constitute the summed d.c. voltage output. The associated method regulates the pulse width of the step-up converter of each converter cell in such a way that the power output of the converter cell fluctuates around the actual theoretical maximum value.
