The invention relates to a method () for controlling an inverter (), wherein the inverter () converts a DC voltage into a multi-phase AC voltage in order to power an electric machine (). The method comprises the following steps: determining () an electrical frequency (f_el) of the electric machine (); determining () a target_switching frequency (f_p_s) for a pulse-width modulation, wherein the target_switching frequency (f_p_s) is synchronous with the determined electrical frequency (f_el) of the electric machine; specifying () a target_start angle (alpha_s) of a first voltage indicator of the pulse-width modulation in relation to the stator-fixed alpha axis, or to one of the basic voltage indicators; controlling () the inverter () by means of pulse-width modulation using the determined target_switching frequency (f_p_s) and the specified target_start angle (alpha_s).
