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.
