A method for controlling a variable speed drive comprising Ni low-voltage power cells connected in series for each phase among multiple phases, i being a phase index. The method comprises repeating P iterations comprising: activating at least one cell of one or more phases and deactivating the other power cells of the variable speed drive, wherein the at least one activated cell is selected on the basis of predefined activation controls depending on an iteration index; and receiving at least one output voltage of the variable speed drive across the terminals of the electrical device for at least one phase. The method further comprises, at the end of the P iterations, determining, from the measured output voltages, values of rectified voltage at the output of respective rectification stages of the power cells, and storing the rectified voltages obtained, which are respectively associated with the power cells.
