    • The invention relates to a method (60) for controlling an inverter (10) using space-vector pulse width modulation, in particular to control an electric machine (14), said inverter (10) being equipped with a plurality of controllable switches (S) and being designed to provide a polyphase electric current (IU, IV, IW), in particular to supply multiphase electric current to an electric machine (14). In said method, a reference phase angle (alpha_R) is predefined, and the inverter (10) is controlled in such a way that a plurality of different successive switching states (V0-V7) is established for the switches (S) in order to provide the electric current (IU, IV, IW) in the form of a current space vector (I*). The inverter (10) is controlled in such a way that the current space vector (I*) is provided at a phase angle (alpha_I) which differs from the reference phase angle (alpha_R), a difference (delta_I) of the phase angle (alpha_I) from the reference phase angle (alpha_R) being determined according to a power loss (PA, PB, PC) and/or a temperature (TA, TB, TC) of at least one of the switches (S).
