Abstract: A method for balancing in a multi-phase DC-DC converter, wherein at least two cells are provided, in each of which at least two phases of the DC-DC converter are grouped, wherein an operation of the individual cells is correlated with respective cell operating values, and an operation of the individual phases is correlated with respective phase operating values, and for balancing, an at least two-stage regulation is carried out with the steps: modulating the phase operating values of the phases as per a first regulation so that the phase operating values are modulated within the cell, and/or modulating the cell operating values of the cells as per a second regulation such that the cell operating values are modulated among themselves.

Abstract: Described is a method for operating a converter for a system for generating electrical energy. In an embodiment of the method, the output voltage of the converter is converted to a d, q coordinate system, wherein the d, q coordinate system is assigned to the frequency of the voltage for the energy supply grid. A desired value is furthermore specified in the d, q coordinate system, several momentary or future values are determined from the output voltage in the d, q coordinate system for different switch positions of the converter, deviations between the desired value and the momentary or future values are determined in the d, q coordinate system, and the converter is switched to one of the switch positions in dependence on these deviations.
